xrun timing check

Hi,

I have to perform an RTL simulation using some library cells and some models. Both files have the timing information through specify/specparam definition.

I would like to suppress timing information for the library cells but I want to keep the timing information relative to my models; so I cannot use the -nospecify option during simulation, otherwise all the timing information will be cleaned.

Is it possible to remove the timing information from only some blocks?

I've also tried to precompile the library using -makelib -nospecify options but it doesn't work. 

Thanks!
