There are a few issues we keep seeing with the Specctra auto router and were wondering if there's any way we can change the constraints or modifications we can make to our DO file to avoid them from happening.
1. Via placement on the differential pairs is weird. It seems when the router puts the differential pair through a via, instead of doing something nice and symmetric, it does something like shown here,
2. Tuning forks get placed somewhere in the middle of the trace instead of near the corner or join that caused the mismatch. Is there a way to constrain how far along the trace before it puts the tuning trombones?
3. Also, is there a way to change the sizes of the tuning trombones? We'd like to do something like this,
Thanks in advance for any advice
