Library standard functions: universal asynchronous receiver/transmitters (UARTs), programmable communications interface, direct-memory access (DMA) controller, parallel port controller Optimized Altera® MAX® FLEX® device architectures Fully verified tested MAX+PLUS® third-party environments Full design entry support MAX+PLUS well third-party tools, including tools from Cadence, Mentor Graphics, Synopsys, Viewlogic Simulation models VHDL Verilog HDL, which support functional verification third-party tool environments MAX+PLUS simulation vectors that demonstrate functionality each MegaCorefunction
General Description
Microperipheral MegaCore Library includes several UARTs, programmable communications interface, controller, parallel port controller. Microperipheral MegaCore Library been pre-tested, documented, licensed Altera MAX+PLUS migration product. These functions optimized architectural features Altera devices, ensuring that user-specified performance utilization goals met. MegaCore functions reduce design task creating only custom logic surrounding these commonly used system-level functions, dramatically shortening design cycle. These functions permit designers focus more time energy improving differentiating final product, rather than redesigning common off-the-shelf functions from ground Altera provides files necessary design with Microperipheral MegaCore Library functions, including:
post-synthesis Altera Hardware Description Language (AHDLTM) design file design implementation target Altera device Test vectors simulation MAX+PLUS VHDL Verilog functional simulation models verification with standard simulation tools

Using Microperipheral MegaCore Library Functions
Designers MAX+PLUS tools design simulate these functions. MAX+PLUS design flows, designer simply instantiates function design file. design flows that third-party tools, designers instantiate MegaCore function specifying function port names hardware description language (HDL) design file. MAX+PLUS compiles resulting EDIF netlist file desired Altera device architecture. designer MAX+PLUS control compilation procedures. example, designers specify timing performance requirements that critical path requirements during place-and-route. Vector Files (.vec) containing simulation vectors these functions provided \megacore directory MAX+PLUS CD-ROM.
Evaluating MegaCore Functions Using OpenCore Feature
Designers preview Microperipheral MegaCore Library functions before purchase OpenCorefeature. This pre-purchase evaluation system allows designers instantiate simulate MegaCore functions with MAX+PLUS software. However, programming files output files third-party tool simulation only generated with authorization code provided upon purchase library.
