WebNov 15, 2016 · We ran across an issue when updating registers containing W1C fields. Specifically, if any field of the CSR requires an update, then calling the parent register's update() results in all W1C fields being written with 1. Example: register CTL has field GO with access type W1C in bit 31. It has field CMD with access type RW in bits 3:0. WebTest cases, firmware, device drivers, and DUT configuration code use this model to access the registers and memories through an object-oriented abstraction layer. Predefined tests also use this model to verify the functional correctness of the registers and memories.
