A truly VLSI circuit is going to be a bear to simulate in any SPICE. That's a lot of nodes. And if you want every gate in it to toggle at some point in an application-realistic worst case sort of way, that could be a whole lot of test vectors. Figuring about one vector per gate being a rough norm for a full coverage test pattern, clock period, do t
The IDDQ target is to cover maximum no of states for each logic gate in given design. we no need to observe any fault outside. Hence is just a toggle profile. due to these reasons the IDDQ coverage is high with lesser patterns.
Hello, I want to exclude bits in toggle coverage. I m working on cadence (iccr) tool. I used this "set_toggle_excludefile" command in coverage configuration file has .ccf extension. I created two file one exclude_bits.ccf and other one is exclude_file.dat. contents of exclude_file.dat. file: -ere instance (...)
yes,you can't say verification is completed for design and you can say only that i have done verification of some percentage(%)... the percentages based on your verification strategies. like if you done branch coverage you can say how many branches have you exercised successfully, if you done toggle coverage you can say how much % of (...)
My design run with VCS 7.0 report toggle rate is 0. The cm.log message is following : Starting toggle coverage for module RM5012_SIM_TOP.RM5012.TOP.RM5012_TOP_ROM : Starting toggle coverage for module RM5012_SIM_TOP.RM5012.TOP.RM5012_TOP_ROM.u_dafilter_top : Starting toggle (...)
What's the Significance of toggle coverage in Code coverage. Why we need toggle coverage. What's the use of this and Where is the application.
Hi all, I am just wondering, do we need to run the code coverage at the gate-level netlist? Can the code coverage from cadence support code coverage at the gate-level netlist? Thanks To a limited extent yes. For instance: * toggle cov on important nets * FSM coming out of reset properly Yes, Cad
You can just add pin constraints on the reset signal. that is set the pin to the constant value and it will not toggle in the at speed test.
I am trying to generate severate coverage reports and merge them after that. This error appear when I merge it and produce a report. I have no idea what it means and I am notsure whether the coverage report generated actually reflects the true result. What I did was: vlog -cover bst -f ../; vsim -c -coverage tbench -do (...)
hi, Firstly, u need to compile ur design file with ur selected coverage. For example, ModelSim > vlog -cover bcst file_name.v Here, ur coverage are b=branch, c=condition, s=statement and t=toggle. then, ModelSim > vsim -coverage file_testbench.v next, run -all. OR, u can enable it using GUI. U go to (...)
The coverage have two .the first is code coverage, if you use some coverage tools , you should see such as: condition coverage , code coverage , brach coverage, toggle coverage and more. when you verify , you should reach 100% of those, the tools manual (...)
Hi, all, I was try to get good toggle coverage for my design!!! Here were some reports from VCS ----------------------------------------- MODULE top.mydesign.sub_design_1 // Net coverage // Name toggled 1->0 0->1 mpu_addr (...)
Modelsim also provide code coverage covering statements, branch, expression and toggle coverage. I find it quite user friendly, just need to compile with the coverage options that you want and then simulate by turning on coverage, interactively or script driven.
Hi Verilog code-coverage utility Covered is a Verilog code-coverage utility used for Design Verification which is capable of performing line, toggle, combinational logic and finite state machine (FSM) coverage analysis. 1. 2. -> t tnx
