  1. I am trying to verify 8 bit RW registers and in some of the registers 4 bits are RESERVED lets say [3:0] . My bit bash sequence tries to write in these constant bit and flags me a mismatch error in the DUT and Mirrored Value. How do i stop my bit bash sequence from checking these RESERVED bits of a register. Thanks for your help
  2. Hi, How to handle memories wide 8 bits in my register model when register map is built with 32 bits width? Thank you Kristina
  3. Hello, I was wondering if are there any resources (papers, blogs, posts, best practices) about methodologies to implement UVM RAL for "large" designs (>100K registers and 50K rams)? I tried to do some research online but most of the results never cover "large" designs. I have experience using RAL and doing some customisation to make it work in a particular environment (callbacks, maps, defining specialised registers, sequences) but most of them were "little" (1K regs and 100 rams) I'm interested on any information about aspects such as: Reg model re-usability and portab
  4. Hi, I have an issue where teh DUT returns an X for register read but the reg2bus still sees it as a 0. When I was going over the uvm_reg_bus_op struct the type for data is uvm_reg_data_t which is only 2-state. Is there a way to override this argument to support 3/4-state? Maybe uvm_reg_data_logic_t? Please let me know. Thanks in advance! Vignesh
  5. I recently came upon an issue where attempting to write a memory via a backdoor yields a warning similar to the following: "reporter [RegModel] Memory 'tst_reg_blk.test_mem' is not contained within map 'Backdoor' (called from get_access())" In addition to the warning, it appears that due rw.map being overwritten (as explained in the second link), Read-Only memories can be written to via the backdoor, since get_access end up returning the default value of "RW". This appears to be in conflict with the Spec: Researching this warning turned up a couple prior forum posts from 201
  6. Hi All, I am working in verification. Where i have to generate reg_block for all the IP's using IPXACT. also top level reg_block which instantiates all the IP level register block using IPXACT. But i am not interested in Ports/Businterface/component. Please advise me what is the best method to do it. Thanks Saravanan
