A UVM/SystemVerilog Testbench for an LDO Voltage Regulator

Check out this UVM testbench that performs the line/load transient & regulation tests and IDDQ & PSSR measurements on a low-dropout voltage regulator circuit in a single run.

Model of the Month

Modeling a digital buffer with adjustable rise and fall delays

Can you model a buffer stage of which rising and falling delays are individually adjusted by digital inputs?

Tip of the Month

Fixing coarse-resolution waveforms displayed with third-party waveform viewers

Got stair-case waveforms when viewing xreal-type signals with PrimeWave or ViVA? Well, it's not XMODEL to blame.

Primitive of the Month

slice

This primitive continuously compares the two xreal-typed inputs and produces an xbit-type output indicating which one is higher.
