As a result of the shift to global design centers and the reduction in time designers spend on each process node, it is no longer always accurate to assume that experienced designers will be working with PDKs.
Reference-tool flows and process-design kits have been the basis of chip design since the start of the semiconductor industry. Although these files provide adequate information, they alone do not represent all of the issues.
The pervasive trends of manpower reduction and the shift toward the use of foundry services have created a new set of challenges for designers attempting to bring a prototype design to reality.
GUEST OPINION: Plenty of commentary has been written about the promise of ESL and how it remains unfulfilled. The truth is that engineers have been successfully designing with ESL tools for years.
Most of the custom chips today, including ASICs, ASSPs (application-specific standard products), and special-purpose custom chips, have function blocks that do not require leading-edge processes.
