How to find the reg and net in the always block

[Donmar001]

if i want to know the driver of the reg signal,what should i do?

Not sure what you'd like to get. If you need to get the list of signals, vpi (or vhpi) is the interface to use.

For example,I want to get the Driver of the reg in the always block.If u use the vpiDriver,you cannt get the driver,it will return the null.
