i got this file a.v it is a netlist verilog file , but a huge module in it for example module xxx has some problems ,now i have a file b.v contains the right module xxx , now i want to replace the xxx module in a.v with the module in b.v

I am doing simulation with VCS , is there any way i can do it ? really need you help
 

You just need to recompile the file b after the file a. If the module xxx is identical, I mean same port name and dimension, this one should replace the previous compile in file a by the module in file b.
 
sir , i know what you mean ,but i don't know what exactly to do . i have file testbench.v a.v(contains the wrong module ), file b.v（contains the right module ） ,can you show me what to do ? appreciate your help

i did it like this vcs +v2k -debug_all +v2k testbench.v a.v b.v -v lib.v seems right , is this all right?
 

if the compile order is garantue as you wrote, yes, that will work.
or you could used three commands to compile separatly the files.
