Integrate 2 memories case, can share one TPG in this case?

Post by iSTART »

[Question] To avoid routing congestion problem, we will combine two memories, for example 8K + 8K, and treat as one 16K memory. In such case, can these two memories share one TPG.

[Answer] For this case, user can use UDM (user define memory) file to define this combined memory.
In BFL file, these two memories should be skipped, so designer can use option “skip_bist_blcok” to highlight these two memories do not insert MBIST.
iSTART also can provide customized design for user to accomplish this design.
