Before delving into debugging, it is critical to have a solid understanding of the basics of SystemVerilog constraint randomization. Constraints are used to define the valid range of value for variables and ens
In the next section, we'll look into more examples using SystemVerilog constraints.
Fourier transform converts a signal from its original timing domain to a format in the frequency domain and also the other way around. In this project, a 4 point FFT has been designed and verified using System Verilog. System Verilog concepts such as randomized constraints and assertions are ...
Randomization adds more devilry So far this about being careful with calculations in SystemVerilog. A generally good practice whether or not you’re using those expressions in constraints. However it’s one thing to carefully reason your way through each sub-expression when you can reason about v...
Since the constraint solver is so powerful, it is interesting to use it in reverse gear. Due to a SystemVerilog feature, it is possible to use it as a versatile checking engine. E.g. after monitoring a transaction, you can use the existing constraints to determine the transaction kind, ...
