4.2i VHDL - Functional simulation fails when I use the PPC405

Description

Keywords: PPC405, functional simulation, ModelSim, VHDL

Urgency: Standard

General Description:
When I use the UniSims PPC405 model included in Service Packs 2 and 3, simulation errors occur and functional simulation fails.

Solution

You can avoid this problem by using a new UniSim model for the simulation as follows:

1. Download the new model from:
http://www.xilinx.com/txpatches/pub/swhelp/ise4_updates/unisims.zip

2. Unzip the ".zip" file into a temporary directory.
3. Compile the two files into the UniSim directory. For MTI, use the following commands, and run them in a command prompt from the temporary directory:

vcom -work unisim unisim_SMODEL.vhd
vcom -work unisim unisim_VCOMP.vhd
