I'm trying to get decent performance out of a design, and the gap between the slow and fast corner is massive. But I don't really need the full quasi-military range of -40/125 and 4.5/5.5 ; I'm replicating a chip whose original specifications were for 0/70 and 4.75/5.25.
Is there any plan to characterize additional corners with reduced range, like 0/85 and 4.75/5.25 that would help with timings for devices intended for commercial rather than industrial/military use?

A sidenote.
The voltage range for the corners includes both external voltage drop and on-chip voltage drop. I have seen total +/- 10% with dividing it equally over both e.g. 5% external and 5% on-chip. This matches to have 4.5/5.5 spec no-chip for external vdd spec of 4.75/5.25.

@Melkhior Characterization of the 5V cells comes from the foundry, don't expect an update.

Unless you plan to migrate to your own maskset and tape out millions of parts, having improved level of detail is probably not that useful?
