Getting up-to-date libraries for timing simulation

[valentin tihomirov]

I have compiled a design with XSE 6.1i. It produced post-synthesis/fitting
VHDL model. ActiveHDL 6.1 simulator fails compilation with *Unknown
identifier "X_ROC"* error. X_ROC is the only primitive that cannot be found
in the SIMPRIM library provided with ActiveHDL. What is the standard
procedure of getting up-to-date libraries: asking library sources from
Xilinx or precompiled .lib file from Aldec? Simulator vendors somehow
optimize pre-compiled libraries.

Consider writing your own vhdl code and
siming it before synthesis.

Excuse me, what does this mean? BTW, I have resolved the problem by

downloading last version (6.2) of SW from Aldec.
