#131576 - re: schematic programs
Responding to: ???'s previous message
Brett Wallace said:
I'm currently working in a very small company and looking for some software to put my schematics in. I don't need to do any layout at the moment as we have another company that does this for us. The previous Electrical Engineer was using Powerpoint to do his stuff bectause he knew the person doing our layout for years and he wasn't big on software.


The previous EE wasn't big on software or the layout person? In any case, the person who's not big on software oughta be fired. We don't do drafted schematics and rubylith layouts any more for a reason.

I would like something more professional then this but I don't have any experince with schematic programs really. The company is small so I can't really get any programs (nor do I probably need) like Altium or Orcad. Does anyone have any suggestions?


Some thoughts:

a) tossing a run of PCBs because you chose the cheapest "tools" is false economy.

b) forcing (hopefully) well-paid engineers and layout people to jump through hoops (spend more time doing something) because you chose the cheapest "tools" is false economy.

c) choose a schematic tool whose netlist output is compatible with whatever the layout people use. No human intervention should be used to get the netlist in shape for layout.

d) choose a schematic tool that can accept a back-annotated netlist. For example, after completing a layout, I like to re-do the ref deses such that they're geographic (this makes trying to find something on the board reasonably easy), so after changing the ref deses you have to back-annotate this to the schematic.

e) Libraries are your friends.
