That's all fine and there is a lot of value in only saving a subset of the outputs, but also there are times when someone might run a sim which takes 2 days and needs the ability to do a fair amount of trouble shooting on the results. I'd rather have used up 15 Gb of disk space and have the data than wait 2 more days because I didn't save that one critical waveform. It is still true that 99.9% of the data in that file is probably not useful, but it is a question of nailing that 0.1% before simulating. I do realize that gnucap can provide even more outputs that just the node voltages so maybe the compromise is to not save all of those. -Dan _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
