To set up the VHDL Output File(.vho) that contains device-wide reset or device power up signals, type the following commands in the ModelSim software main window before starting simulation:
force /<design>/<entity>/<device power up> 0 0 ns 
force <design>/<entity>/<device power up> 1 <time> ns 
force /<design>/<entity>/<device-wide reset> 1 0 ns 
|
|
Note: The variable <device-wide reset> is the name of the device-wide reset signal, <device power up> is the name of the device power up signal, and <time> is a time value between 0 and the actual starting time of the simulation. |
