Q: I want to save the state of my simulation, so that I don’t have to keep running my dorky setup command file every time. How can I do this?
There are 2 ways to save the state of a simulation in irsim. The first way saves the state of the sim as well as the history. The second way only saves the state.
The command dumph will dump the history of the simulation to a specified file. The readh command will read that history back out. Please take a look at the irsim manual page for specifics.
The > command will write only the state (not the history) of a simulation to a file. The < command will read this back out. This is especially useful for running very long tests, where the history buffer of irsim gets huge. You can break up your test and at the end of each piece, write the state to a file. When you start up the next piece, just read that state back in.
Q: I have a vector nodes from a7 to a0. Is there easy way to define vector without typing all vector nodes?
vector A a{7:0} is equivalent to
vector A a7 a6 a5 a4 a3 a2 a1 a0 - In the analyzer window you can print the graph to postscript using the print|file option (obviously)
