Don’t use that tone – checklists
It should be clear to all that a tape out check list is essential (see Quality babel fish and ROMs, checklists and personal responsibility); before you spend $1M+ it is key to know what you are shipping and agree that it

How big should a unit (test) be?
The term “Unit Test” is taken to be the lowest level of testing. How big should this Unit be? If we looked to software for the answer with Test Driven Development and Uncle Bob’s maximum four line function, then a

Unmanufactured CAD sub layers
Lesson learnt Make sure that your LVS deck only uses manufactured layers to provide connectivity. Otherwise the LVS result may not be valid. The tale We had got to within hours of tape out. The chip needed to go, for

Only two reasons..
Back in 2013 I presented to Mike Bartley’s “Future Verification”conference in Reading, UK. In this I boldly claimed that there were only two reasons for silicon failure: The ASIC model failed or The feature was not verified It was slightly odd

Beginners guide to debugging silicon
A two minute guide.. If you freeze spray the device and it changes behaviour you have a bug, And it is most likely a “Broken ASIC model” type bug. If you slow the clock down and it starts to work,
