Don't Miss Out. Start Using the Find Navigator Today

Probably the single best thing you can do to improve the quality of life. Sadly, the UI hasn't improved one iota since 2016 😢 Edit > Find. Then, Operate on the Selection (use the drop down). Else, your life is more complicated - you choose View and then tell it how to filter stuff out. For now, suppose we've selected a bunch of netlabels and want to change <*50>whatever to <*100>whatever (where in the world would you use something like this?) In the Script field : set string [property get -name Name -system] regsub -all {\*50} $string {\*100} string property set Name -system -value $string Now, how in the world are you supposed to know that? Search me. Any surprise that Cadence is the top EDA dog?

Dear Dr. Dev! Do I Really Need to Save All to Be Able to Cross Probe (No, but..)

Image
That's right - if you DON'T save all (pick the dropdown for true in the Spice options for saving voltages or currents) the cross-probing doesn't work out of the box. But, given how expensive saving all IS, what you can do is, copy the .tsub file from a run that DID save all to your just completed run before going to "View Waveforms" from T-Spice to launch the Waveform Viewer. Enjoy, and love to Kathy
