Hi Oliver,
I'm the developer of PCB's toporouter[1]. I have a few questions, if
you don't mind:
- Do you mind curvilinear wiring?
- How many power supplies?
- How much are you paying for the job?
- Have the schematics already been captured in gschem?
- Have footprints for components already been captured and verified?
- Can you give me any hints about the complexity of the routing? Is it
really nasty all-to-all stuff? Or is there some structure to it?
Any info you could give me would be appreciated.
Cheers,
Anthony
