It was just the one parameter. I've spent a bit more time thinking about it had another play with it this morning. It seems my problem was in wanting to sweep a resistor value from zero ohms to 3 ohms in 0.5 ohm steps. The first (zero ohm) step is where the problem is caused...... (though a 0R in this position should NOT make any difference) And like I said yesterday - if I *hide* the traces on the graph relating to the parameter sweep, run the simulation, and then view the traces, I get correct results. If I run the simulation without hiding the traces, then the simulation gets stopped on an error. This is still happening. One more item for the bug list? If anyone wants a copy of my ddb with the test schematic and .sdf file then I can email it. However I assume that posting it out to the mailinglist would be bad form. > There are some issues with the simulation but nothing what > would make it unusable.

That's good to hear, because I'm going to need some basic reliable circuit simulation power over the next couple of months. > What makes the > simulator not so nice is the limited capability of the output > (simview). hmm.. yeah though I'm doing OK with the relatively small demo circuits and my own basic stuff so far. > We > use P99 since its release and in the end we were able to simulate any > circuit we wanted (mainly video and filter circuits).

Can anyone running protel simulations recommend a good book to help with spice related issues? thanks, Julian Higginson * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:proteledaforum@;techservinc.com * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:ForumAdministrator@;TechServInc.com * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@;techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
