Post subject: | Simulation- Avoid Unknown Propagation |
GPRs (General Purpose Registers) and USRs (User Special Registers) are implemented without reset to save gate count. In the simulation, one would encounter unknown propagation problems by reading uninitialized GPRs/USRs. To solve this problem, these registers should be initialized to known values as: V3m (N705, N801...) Attachment: Init 1.PNG [ 21.56 KiB | Viewed 19147 times ] V3 (N968, N1068, D1088, N1337...)
