hi

its sad:-( that iam still stuck up with " vsim-vcd-3228 Error vcd simulation " problem for a design.

Meanwhile I am working with another design in Verilog and doing my simulation in Questasim.
when i run the testbench i get an error. Top module:main_design

** ******** *****************************************************************
Error (vsim-3063) ../input/TC_core.v(881): port 'SLEEP_N' not found in the connected module (200th connection)
Region: /tbench/design1/module/main_design

* **** ********************************************************

Sorry that i could not copy the error but i need to type it because i work on the server.

thanks for the help
