Abstract:
A method of debugging an embedded dynamic random access memory (eDRAM) element of a processor core is provided. An aspect includes, based on an error occurring in the eDRAM element, stopping a functional clock, and not stopping a refresh clock. Another aspect includes, based on the functional clock being stopped, creating a fence signal that prevents all commands other than a refresh command, the refresh command being based on the refresh clock, from entering into the eDRAM element. Another aspect includes initializing a line fetch controller of the processor core with at least one of write data and read data. Another aspect includes restarting the functional clock. Another aspect includes performing at least one of write requests and read requests to the eDRAM element based on the at least one of the write data and the read data from the line fetch controller based on the functional clock.
