Conversion of PEEL 22CV10AZ to 22CV10A+
Hi, I've got my hand on a really old design here. I would like to convert a PEEL file which is currently compiled for a 22CV10AZ into a file for a 22CV10A+ device (I think the plus "+" is optional)....

DEFCON in LT-SPICE?
What does DEFCON mean when running a simulation in LT-SPICE? During many simulations, the SPICE engine supposedly goes into DEFCON, and the quality of the results apparently deteriorates. Is something...

PSpice: Display and set simulator options in the schematic (Capture)
Hi. According to... "Flip-flops are set to a value dictated by the value of DIGINITSTATE, which is set from the Global Settings menu, or by a .OPTIONS DIGINITSTATE= command somewhere in the circuit."...

Announcement: Addition to Web Site
From time to time I develop tools and parts for PSpice to ease (and speed up) circuit development. One of my pet peeves has been that DC, F and G current sources will just merrily keep pumping right...

alternatives to EAGLE cad?
Lately I've been annoyed and frustrated with EAGLE. No big problems, just lots of seemingly minor things - like lots of paper cuts. I download Pulsonix's demo many months ago and was impressed that it...
