flexible block RAM, with registers input output ports, that used implement common gate array megafunctions. Because large flexible, suitable functions such multipliers, vector scalars, error correction circuits. These functions combined applications such digital filters microcontrollers. Logic functions implemented programming with readonly pattern during configuration, thereby creating large LUT. With LUTs, combinatorial functions implemented looking results rather than computing them. This implementation combinatorial functions faster than using algorithms implemented general logic, performance advantage that further enhanced fast access times EABs. large capacity EABs enables designers implement complex functions single logic level without routing delays associated with linked field-programmable gate array (FPGA) blocks. example, single implement function with inputs outputs. Parameterized functions, such functions, take advantage automatically. ACEX enhanced supports dual-port RAM. dual-port structure ideal FIFO buffers with clocks. ACEX also support 16-bit-wide blocks. ACEX dual-port single-port mode. When dual-port mode, separate clocks used read write sections, allowing written read different rates. also separate synchronous clock enable signals read write sections, which allow independent control these sections. also used bidirectional, dual-port memory applications where ports read write simultaneously. implement this type dual-port memory, EABs used support simultaneous reads writes.

This feature, called register packing, improve utilization because register used unrelated functions. ACEX architecture provides types dedicated high-speed data paths that connect adjacent without using local interconnect paths: carry chains cascade chains. carry chain supports highspeed counters adders, cascade chain implements wide-input functions with minimum delay. Carry cascade chains connect LABs same row. Intensive carry cascade chains reduce routing flexibility. Therefore, these chains should limited speed-critical portions design.

Carry Chain
carry chain provides very fast carry-forward function between LEs. carry-in signal from lower-order drives forward into higher-order carry chain, feeds into both next portion carry chain. This feature allows ACEX architecture efficiently implement high-speed counters, adders, comparators arbitrary width. Carry chain logic created automatically compiler during design processing, manually designer during design entry. Parameterized functions, such DesignWare functions, automatically take advantage carry chains. Carry chains longer than eight automatically implemented linking LABs together. enhanced fitting, long carry chain skips alternate LABs row. carry chain longer than skips either from even-numbered even-numbered LAB, from oddnumbered odd-numbered LAB. example, last first carries first third row. carry chain does cross middle row. instance, EP1K50 device, carry chain stops eighteenth LAB, carry chain begins nineteenth LAB. Figure shows n-bit full adder implemented with carry chain. portion generates bits using input signals carry-in signal; routed output register bypassed simple adders used accumulator function. Another portion carry chain logic generates carry-out signal, which routed directly carry-in signal next-higher-order bit. final carry-out signal routed where used general-purpose signal.

Cascade Chain
With cascade chain, ACEX architecture implement functions that have very wide fan-in. Adjacent LUTs used compute portions function parallel; cascade chain serially connects intermediate values. cascade chain logical logical (via Morgan's inversion) connect outputs adjacent LEs. With delay each additional provides four more inputs effective width function. Cascade chain logic created automatically compiler during design processing, manually designer during design entry. Cascade chains longer than eight bits implemented automatically linking several LABs together. easier routing, long cascade chain skips every other row. cascade chain longer than skips either from even-numbered even-numbered LAB, from odd-numbered odd-numbered (e.g., last first cascades first third LAB). cascade chain does cross center (e.g., EP1K50 device, cascade chain stops eighteenth LAB, begins nineteenth LAB). This break EAB's placement middle row. Figure shows cascade function connect adjacent form functions with wide fan-in.

Normal Mode normal mode suitable general logic applications wide decoding functions that take advantage cascade chain. normal mode, four data inputs from local interconnect carry-in inputs 4-input LUT. compiler automatically selects carryin DATA3 signal inputs LUT. output combined with cascade-in signal form cascade chain through cascade-out signal. Either register used drive both local interconnect FastTrack Interconnect routing structure same time. register used independently (register packing). support register packing, outputs; drives local interconnect, other drives FastTrack Interconnect routing structure. DATA4 signal drive register directly, allowing compute function that independent registered signal; 3-input function computed LUT, fourth independent signal registered. Alternatively, 4-input function generated, inputs this function used drive register. register packed still clock enable, clear, preset signals packed register drive FastTrack Interconnect routing structure while drives local interconnect, vice versa. Arithmetic Mode arithmetic mode offers 3-input LUTs that ideal implementing adders, accumulators, comparators. computes 3-input function; other generates carry output. shown Figure first uses carry-in signal data inputs from local interconnect generate combinatorial registered output. example, adder, this output three signals: carry-in. second uses same three signals generate carry-out signal, thereby creating carry chain. arithmetic mode also supports simultaneous cascade chain. Up/Down Counter Mode up/down counter mode offers counter enable, clock enable, synchronous up/down control, data loading options. These control signals generated data inputs from local interconnect, carry-in signal, output feedback from programmable register. 3-input LUTs used; generates counter data, other generates fast carry bit. 2-to-1 multiplexer provides synchronous loading.

Synchronous loading provided 2-to-1 multiplexer. output this multiplexer with synchronous clear signal.
Internal Tri-State Emulation
Internal tri-state emulation provides internal tri-states without limitations physical tri-state bus. physical tri-state bus, tri-state buffers' output enable (OE) signals select which signal drives bus. However, multiple signals active, contending signals driven onto bus. Conversely, signals active, will float. Internal tri-state emulation resolves contending tri-state buffers value floating buses high value, thereby eliminating these problems. Altera software automatically implements tri-state functionality with multiplexer.

Either LABCTRL1 LABCTRL2 control asynchronous clear. Alternatively, register that LABCTRL1 implements asynchronous load. data loaded driven DATA3; when LABCTRL1 asserted, DATA3 loaded into register. During compilation, compiler automatically selects best control signal implementation. Because clear preset functions activelow, Compiler automatically assigns logic high unused clear preset. clear preset logic implemented following modes chosen during design entry:

Asynchronous Preset Clear When implementing asynchronous clear preset, LABCTRL1 controls preset, LABCTRL2 controls clear.

FastTrack Interconnect Routing Structure
ACEX architecture, connections between LEs, EABs, device pins provided FastTrack Interconnect routing structure, which series continuous horizontal vertical routing channels that traverse device. This global routing structure provides predictable performance, even complex designs. contrast, segmented routing FPGAs requires switch matrices connect variable number routing paths, increasing delays between logic resources reducing performance. FastTrack Interconnect routing structure consists column interconnect channels that span entire device. Each LABs served dedicated interconnect. interconnect drive pins feed other LABs row. column interconnect routes signals between rows drive pins. channels drive into local interconnect. signal buffered every reduce effect fan-out delay. channel driven three column channels. These four signals feed dual 4-to-1 multiplexers that connect specific channels. These multiplexers, which connected each allow column channels drive channels even when eight drive interconnect. Each column LABs EABs served dedicated column interconnect. column interconnect that serves EABs twice many channels other column interconnects. column interconnect then drive pins another row's interconnect route signals other LABs EABs device. signal from column interconnect, which either output input from pin, must routed interconnect before enter EAB. Each channel that driven drive specific column channel. Access column channels switched between adjacent pairs LABs. example, drive column channels normally driven particular adjacent same row, vice versa. This flexibility enables routing resources used more efficiently. Figure shows ACEX LAB.

Pull-Up Clamping Diode Option
ACEX devices have pull-up clamping diode every I/O, dedicated input, dedicated clock pin. clamping diodes clamp signal VCCIO value required 3.3-V compliance. Clamping diodes also used limit overshoot other systems. Clamping diodes controlled pin-by-pin basis. When VCCIO that clamping diode option turned driven 2.5-V 3.3-V signal, 5.0-V signal. When VCCIO that clamping diode option turned driven 2.5-V signal, 3.3-V 5.0-V signal. Additionally, clamping diode activated subset pins, which allows device bridge between 3.3-V 5.0-V device.
Slew-Rate Control

Designers specify slew rate pin-by-pin assign default slew rate pins device-wide basis. slow slew rate setting affects only falling edge output.
Open-Drain Output Option
ACEX devices provide optional open-drain output (electrically equivalent open-collector output) each pin. This open-drain output enables device provide system-level control signals (e.g., interrupt write enable signals) that asserted several devices. also provide additional wired-OR plane.
MultiVolt Interface

Power Consumption
supply power ACEX devices calculated with following equation: PINT (ICCSTANDBY ICCACTIVE) ICCACTIVE value depends switching frequency application logic. This value calculated based amount current that each typically consumes. value, which depends device output load characteristics switching frequency, calculated using guidelines given Application Note (Evaluating Power Altera Devices). Compared rest device, embedded array consumes negligible amount power. Therefore, embedded array ignored when calculating supply current.

Value
This supply power calculation provides estimate based typical conditions with output load. actual should verified during operation because this measurement sensitive actual pattern device environmental operating conditions. better reflect actual designs, power model (and constant power calculation equations) continuous interconnect ACEX devices assumes that drive FastTrack Interconnect channels. contrast, power model segmented FPGAs assumes that drive only short interconnect segment. This assumption lead inaccurate results when compared measured power consumption actual designs segmented FPGAs.

Configuration Operation
ACEX architecture supports several configuration schemes. This section summarizes device operating modes available device configuration schemes.
Operating Modes
ACEX architecture uses SRAM configuration elements that require configuration data loaded every time circuit powers process physically loading SRAM data into device called configuration. Before configuration, rises, device initiates Power-On Reset (POR). This event clears device prepares configuration. ACEX time does exceed When configuring with configuration device, refer relevant configuration device data sheet timing information.
Altera Corporation
ACEX Programmable Logic Device Family
During initialization, which occurs immediately after configuration, device resets registers, enables pins, begins operate logic device. Before during configuration, pins (except dedicated inputs, clock, configuration pins) pulled high weak pull-up resistor. Together, configuration initialization processes called command mode; normal device operation called user mode. SRAM configuration elements allow ACEX devices reconfigured in-circuit loading configuration data into device. Real-time reconfiguration performed forcing device into command mode with device pin, loading different configuration data, re-initializing device, resuming user-mode operation. entire reconfiguration process requires less than used reconfigure entire system dynamically. In-field upgrades performed distributing configuration files.
Configuration Schemes
configuration data ACEX device loaded with five configuration schemes (see Table 59), chosen basis target application. EPC16, EPC2, EPC1, EPC1441 configuration device, intelligent controller, JTAG port used control configuration ACEX device, allowing automatic configuration system power-up. Multiple ACEX devices configured five configuration schemes connecting configuration enable (nCE) configuration enable output (nCEO) pins each device. Additional APEX 20K, APEX 20KE, FLEX 10K, FLEX 10KA, FLEX 10KE, ACEX FLEX 6000 devices configured same serial chain. Table Data Sources ACEX Configuration Configuration Scheme
