Abstract
The disclosure provides using test processors to provide a more flexible solution compared to the existing DFX blocks that are used for controlling test networks in chips. The test processors provide a highly flexible solution since programming of the test processors can be changed at any time; even after manufacturing, and can support practically an unlimited number of core chips in any configuration. The high flexibility provided via the test processors can reduce engineering effort needed in design and verification, accelerate schedules, and may prevent additional tapeouts in case of DFX design bugs. By making debug and diagnosis easier by providing an opportunity to change debug behavior as needed, the time-to-market timeline can be accelerated. Accordingly, the disclosure provides a chip with a test processor, a multi-chip processing system with a test processor, and a method of designing a chip having a test processor.
