'CMPY_V2_1' is not defined

[gsm19780510]

Hello,everyone.

    I have synthesised the cmult IP and added it to a verilog model. The process of synthesis is correct. But, when i simulated it in modelsim 6.3c, these error occured: vsim work.one2two # vsim work.one2two # ** Note: (vsim-3812) Design is being optimized... # ** Error: mult.v(85): Module 'CMPY_V2_1' is not defined. # Optimization failed # Error loading design

Did someone have this problem and solved it, please give me some help. Thank you! Kudos! Thanks!

Did you compile the simulation libraries (CoreGen in particular)? When you run vsim, did you include XILINXCORELIB in your library search path?

Cheers,

Jim

hello,Jim

     this problem have been solved. the reason is that the vhdl library not loaded when i turn on the modelsim from ISE. I added the vhdl library to the modelsim library again by manul. the problem is solved.
