How to start Questa sim/prime disabling threads

Question asked by praveenamarapalli on Mar 10, 2015

Hi,

 

When I am compiling a project on Grid which has lot of memory, vsim is creating lot of threads hence the compilation is failing.

 

Can some one please help how to start Questasim (vsim) which can run only on single thread (or disable threads option)

 

This project is being compiled in coordination with other tool Calypto catapult.

 

Compiling C++ file: ../../tb_dct_stream.cpp
