SIMPRIMS - Alliance 2.1 differs from 1.5i (or older) for Verilog SIMPRIMS simulation

Description

Keywords: Alliance, SIMPRIMS, Verilog

Urgency: Hot

General Description:
The format and usage of the SIMPRIMS Verilog simulation libraries have changed
from the previous version of the software.

The SIMPRIMS library is used for post-NGD2VER simulation after NGDBUILD,
MAP, or PAR. The library also contains generic simulation primitives.

Please see (Xilinx Solution 6534) for information regarding changes to the UNISIMS library.

Solution

1. The file extensions have been changed from .vmd to .v.

2. Port names were changed from IN* to I* and OUT* to O* to coordinate with
the VHDL models, as "in" and "out" are reserved words in VHDL.

Therefore, any LogiBLOX modules generated in 1.5i will not simulate using the 2.1i
SIMPRIMS libraries.

3. The library location for the SIMPRIMS library in 2.1i is
$XILINX/verilog/src/simprims/*.v
