There is no information here with which to answer. How many instances? How about a test case?

[marcozhuang21]

the project is a riscv core : https://github.com/T-head-Semi/openc906
i think the gates is less than 1M counts

[marcozhuang21]

i test two platforms , the same question.
(1) i cp designs/nangate45/tinyRocket as c906 and change config.mk and sdc
(2) i cp designs/asap7 as c906 and change config.mk and sdc
open_test.zip

Please put together a self-contained test case. 'make global_place_issue' will build one.

[marcozhuang21]

i build the test case as follow:
