I've been using ExpressSCH for all of my analog board schematics and for some of the other misc TAU analyzer schematics.
Bob [Feretich] has been using a different tool, he might have some comments.
Express SCH Pros:
- Free
- seems bug free
- pretty good component library, certainly most everything is discrete on the IBM cards
- can define your own components
- easy to move things about, rubber band connections, can cut and paste
- pretty easy to learn
- permits different page sizes
Cons
- No net list out of SCH, I haven't tried the PCB, maybe it will produce one for checking the layout
- proprietary file format, I use acrobat to output PDF's for interchange
- unusual typeface, doesn't ocr well in acrobat
- no ascii data input format I know of
- I manually edit off the R,C etc indentification of resistors and capacitors
- a few shortcuts can increase entry productivity
- no 74HC in factory supplied library but some 74LS, so I change the names on the pin compatible parts
- (I haven't been able to find any other libraries - does anybody know of some on the web?)
I've attached the most complex schematic for the analog board (1 of 3) which is mixed 74HC and discrete components
