Specman 9.2 64 bit

Brian M

 Hello All,

 

Does specman 9.2 have a environmental variable that you can use instead of a command line switch (-64)?

Can  you run specman 64 bit with modelsim (Mentor) in 32 bit mode and/or the other way around?

Thanks

Brian Miller

  • Hi Brian.

    As far as I'm aware, you'd need to have bothSpecman and your simulator (whatever vendor it comes from) in the same 32/64 bit configuration. Ususally Specman is loaded intot he simulator as a shared library and there's no way to load a 64-bit library into a 32-bit exe.

    As for the environment variable for 64-bit mode, up to Incisive 9.2 the env.csh / env.sh supports a -64bit option so set the tool into 32/64 by default. From 10.2 onwards, the env.csh is deprecated and I admit I'm not sure what you'd do for linking with Modelsim in this case. I guess you just need to set the right LD_LIBRARY_PATH to teh 32/64 bit libraries in the Incisive installation.

  • You can try using CDS_AUTO_64BIT variable but no guarantees:

    setenv CDS_AUTO_64BIT ALL
