Simulating a8251 Model
with Visual Software
June 2000, ver.
Introduction
Altera® intellectual property (IP) MegaCorefunctions developed pre-tested Altera, optimized specific Altera device architectures. test-drive these functions free OpenCorefeature downloading functions from Altera site installing them your UNIX workstation. help your evaluation, Altera also provides Visual simulation models these functions. Visual software from Innoveda lets create simulation models that used third-party VHDL Verilog simulation tools. Altera distributes Visual software user along with Visual models Altera functions. Altera's Visual models parameterizable, level, functional simulation models. models instantiate Altera your design simulate your choice simulation tool. This user guide describes install Visual simulation model Altera a8251 programmable communication interface. Before using a8251 model, must download install Visual software, which available free from Altera MegaStore site Follow instructions Installing Visual Software User Guide. Altera recommends that also obtain a8251 Programmable Communications Interface Data Sheet from Altera site. This data sheet describes technical specifications a8251 function.

Download Models
have already done download Visual models from Altera's site http://www.altera.com following instructions below. Point your browser Search MegaStore function/model wish obtain. search results page, click name function/model wish obtain. Click Free Test Drive icon follow on-line instructions download function and/or model.
Installation
Execute a8251_vip_pc.exe file follow on-line instructions install model. following files installed: <installation path>\vip_simulation\A8251\ doc\ a8251_vipug.pdf verilog\ A8251.v vhdl\ mti\ A8251.vhd leapfrog\ A8251.vhd vss\ A8251.vhd <installation path>\vip_models\a8251\* Before using Visual model, VIP_MODELS_DIR environment variable <installation path>/vip_models. installation process sets other required environment variables system registry.

Altera Visual models VIP_MODELS_DIR environment variable. only wish Visual model, install model into directory variable point that directory. However, wish several models (e.g., both a8251 a8259 models) should install Visual models into same directory.
Solaris Installation
a8251 model tape archive file (.tar) that been compressed using gzip utility. extract files, move a8251_vip_solaris.tar.gz file location which would like install models type following commands UNIX prompt: gunzip a8251_vip_solaris.tar.gz a8251_vip_solaris.tar following directories files created: <installation path>/vip_simulation/A8251/ setup.csh doc/ a8251_vipug.pdf verilog/ A8251.v vhdl/ mti/ A8251.vhd leapfrog/ A8251.vhd vss/ A8251.vhd <installation path>/vip_models/a8251/* Before using Visual models, perform following steps: VIP_MODELS_DIR environment variable <installation path>/vip_models. Altera Visual models VIP_MODELS_DIR environment variable. only wish Visual model, install model into directory variable point that directory. However, wish several models (e.g., both a8251 a8259 models) should install Visual models into same directory.

VIP_EU_ROOT environment variable root directory which installed Visual software. Source setup.csh file complete configuration Visual environment.
Using a8251 Model
This section describes a8251 simulation model your designs.
Verilog
using Verilog HDL, perform following steps: Visual interface described Installing Visual software User Guide. Make sure VIP_MODELS_DIR environment variable properly. <installation directory Compile A8251.v. This module attachs appropriate Visual model using Verilog-XL interface. Instantiate A8251 your Verilog design.
VHDL
using VHDL, perform following steps: Visual language interface described Installing Visual software User Guide. Make sure VIP_MODELS_DIR environment variable properly. the<installation directory, where <simulator> VHDL simulation tool using. Compile A8251.vhd into your work library. This component attaches appropriate Visual model using language interface your VHDL simulator. Instantiate work.A8251(behave) your VHDL design.
