  1. Hi Guys, I am using UVM Register model to mimmick RTL's register implementation. Some registers are not implemented in RTL which are going to be connected to output port of some other module. I have got a HDL path of register as an output port declaration of some module. Something like: The HDL path is: "tb_top.dut_u.interrupt_module_u.o_ext_interrupt" o_ext_interrupt is declared as output port inside interrupt_module, which is not connected to any other wire or register. Can this output port's value be changed by writing to it via UVM BACKDOOR ? I am using following A
  2. Hi, I have a interface monitor where i am capturing data from the interface. I need to pass valid data captured from the interface to the scoreboard for comparison. But the behaviour of interface signals and the way they are asserted depends on the register configuration. Now this config info is not known to the interface or the interface monitor. So while implementing the monitor, should i define two monitors 1) interface monitor which just samples all the data from the bus. 2) process data got in 1) furthur depending on the register config & then pass it on the scoreboard fo
  3. In my earlier UVM days I ran into this confusing error message a number of times. I just hit it again, so am posting my solution here, to share and to help myself rediscover when it is time. Error (running IUS 13.1): uvm_analysis_imp_my_snoop #( xyz_trans, my_scoreboard) my_snoop_port; | ncvlog: *E,EXPENC (/user/goblin_dev/tb/my_scoreboard.svh,60|50): Expecting the keyword 'endclass'. Below is the pseudo code w/o the error. In converting the real code to pseudo code (to make it more succinct and sterilized), I do not believe I created any inconsistencie
  4. I've run into the following issue using the built-in UVM register tests. The built-in UVM register tests (seem to) start R/W-ing immediately after top-level reset is released. This was fine, initially. See attached image "Capture". We now have some delay between the release of top-level reset and the actual reset going to the register block. This is resulting in a read occurring before reset to the rtl regblock is released, and causes the test to hang. See attached image "Capture2". Without modifying the built-in register tests/sequences, how would anyone suggest that we cleanly
  5. Not sure do you have similar problem? I have a problem in handling the reset value in RAL. f the reset value of a field in the register is don't care, what can I do for it? Now my plan is extend a new access type. For this kind of registers, the read value in reset test is not checked. Do you guys think it is a feasible way? Thanks.
  6. One aspect that was not covered in the UVM Basics series posted by Cadence in May 2012 was the register layer (aka UVM_REG). In this new video series we are giving an overview of the concepts, components and applications of the UVM register layer. The new video series is broken up into twelve clips: Introduction Testbench Integration Adapter Predictor & Auto Predict Register Model & Generation IP-XACT Register Model Classes Register API & Sequences Access Policies Frontdoor & Backdoor Predefined Sequences Demonstration You are now registered for success! (sorry, bad pun

  8. Hi I am new to UVM. Can any one provide the sample example for using uvm_post_main_phase? Thanks, Ravi
  9. Dear SystemVerilog/UVM User, I've setup a SystemVerilog Meetup in Silicon Valley for people who are interested in hashing over problems they're having or learning new features in a group setting. http://www.meetup.com/SystemVerilog-Social-Club-Silicon-Valley/ I look forward to seeing you there. all the best, Linc Jepson
