Limitations
•
You cannot release a bit or slice of a register; you can release only the entire register.
signal_release Example
This example releases any forces on the signals data and clk when the signal release_flag is a
"1". Both calls will send a message to the transcript stating which signal was released and when.

$signal_release Example
This example releases any forces on the signals data and clk when the register release_flag
transitions to a "1". Both calls will send a message to the transcript stating which signal was
released and when.
