how do I get a longer simulation time
I have a transfer function I'm graphing on a scope with a step input. There is no time variable in the function restricting the time to 10 seconds, but when I press autoscale on the scope there's no data for more than 10 secs. I tried connecting a random number to a scope and I couldn't get more than 10 seconds worth o... 8 Mar 2010 16:24
