Hai Ayaz, In addition to the previous query, is it possible to determine the page size supported during the simulation in SE mode. I understood that the commMonitor generates the physical address. Whether my understanding is correct. Since address length varies, I had doubts regarding this page size. Traces look like this:
7,r,980,4,256,0 7,r,984,4,256,77000 7,r,988,4,256,126000 8,r,474576,4,10,175000 7,r,992,4,256,238000 7,r,996,4,256,287000 8,w,474576,4,10,336000 7,r,1000,4,256,357000 8,w,474572,4,10,406000 7,r,1004,4,256,427000 8,r,1028,4,10,476000 7,r,1008,4,256,525000 8,w,474568,4,10,574000 On Wed, Feb 15, 2023 at 9:12 AM Sadhana . <sadhana.197cs...@nitk.edu.in> wrote: > Thank you. > > On Tue, Feb 14, 2023 at 4:34 PM Ayaz Akram <yazak...@ucdavis.edu> wrote: > >> Hi Sadhana, >> >> I think the first number is the requestor port id (IIRC).
