What is the test strategy for ARM soft cores?
Applies to: ARM1026EJ-S, ARM1136, ARM7EJ-S, ARM7TDMI-S, ARM926EJ-S, ARM946E-S, ARM966E-S
Answer
The test strategy for ARM soft IP is scan/ATPG, plus BIST for memories. Scan insertion is normally done during synthesis, ARM provide synthesis scripts for this.
An ARM generic BIST controller is usually supplied, this can be substituted for a proprietary BIST controller if required.
TIC testing is not applicable to soft cores and only applies to hard cores
