How to Stop the Simulation on `uvm_error

The default behavior of `uvm_error is to continue the simulation once the message is reported. Although one can argue over Accelera’s default choice, there are ways to stop the simulation on `uvm_error. I’ve tested them with UVM 1.1d and UVM 1.2 releases. Using Simulator Arguments Major simulators support the +uvm_set_action command-line argument to set a […]

Zebra Puzzle is a very good didactic problem for understanding constraints. Tudor Timisescu, the blog’s author, takes the effort in showing us what problems he encountered while building the constraints in SystemVerilog. Verification Gentleman: Fun and Games with CRV: The Zebra Puzzle If you want to know how to constraint elements of a dynamic array […]

Save Time in Pre-Silicon Functional Verification Using Regression Automation Scripts

We do pre-silicon verification in multiple iterations, each iteration including at least a regression. Regressions consume a great deal of HW resources (e.g. CPU time) and SW resources (e.g. licenses) and… a lot of human effort. This is what usually happens when we run a regression: we aim to reduce the time spent in regression […]

Coverage Aware Generation using e Language Normal Distribution Constraints

When defining coverage items we need to make a trade-off between the number of coverage buckets, their size and the simulation time required to get them covered. From our experience the solution is to generate items being aware of how they will be covered. For example if the coverage item has power-of-2 buckets, the generated […]

Migrating to UVM 1.2

A couple of days ago I watched a presentation on UVM 1.2 by Tom Fitzpatrick of Mentor Graphics posted on Verification Academy, and I thought to give it a try and port one of our verification environments based on UVM 1.1d. Here is what my experience has been, originally posted on Accellera. 1. Download UVM […]
