Stop guessing why randomization fails and debug constraints live in Questa

 

Join us at this free Expert Series Webina that will show you how the Constraint Debug Window in Questa One Sim lets you inspect variables, visualize distributions, and isolate conflicting constraints in real time, with a single breakpoint and zero recompilation.

 

 

 

Find, isolate, and fix broken constraints in real time without touching a single line of source code.

When randomize() fails or silently produces the wrong values, tracking down the culprit constraint can take hours.

 

What You Will Learn:

• Enable the Constraint Debug Window and set randomize() breakpoints from the GUI or transcript
• Spot conflicting constraints instantly using red highlighting and the Unsatisfiable column
• Toggle constraint_mode and rand_mode to isolate and disable problematic constraints on the fly
• Run Distribution Analysis to visualize your solution space as a histogram
• Use Value Injection and Binary Constraints to test whether a specific value is reachable

 

Who Should Attend:

• Verification engineers and UVM users working with System Verilog constrained-random testbenches who want to debug randomize() failures faster
