Chip lifecycle / Work products / Critical circuit feasibility study

Critical circuit feasibility study

An early study that checks whether the most demanding circuits can meet their targets in the candidate process before the specification is frozen.

Analysis Work product in the Analog and mixed-signal lifecycle

Why it exists and what it decides

It finds circuits that cannot meet their targets while the specification and process can still change. Found after months of design work instead, an infeasible block forces a late specification change or a costly process switch.

Decisions it informs

Whether the critical targets are achievable in the process
Which circuit topology to pursue for each critical block
Whether the candidate process is suitable for the product
