When designing a new BB
Avoid surprises!
!
Mistakes cost $$$
1. Lost characterization time
2. Delay of ½+ year for new MPW
3. Redesign (personnel/licenses)
4. Cost of new MPW
Bright Photonics (c)
Avoid surprises
1. Use PDK BBs
2. Use X-PDK (GDS)
3. Use design modules (script)
4. From scratch
Your PIC is only as good
as the weakest BB
