Charles Dančak reports a UVM/SystemVerilog testbench for a programmable analog filter

A DVCon U.S. paper by Charles Dančak of Betasoft Consulting extends an object-oriented testbench into UVM for a digitally programmable analog bandpass filter. A fixture encapsulates the DUT and XMODEL stimulus/measurement primitives, while UVM components randomize frequencies and modes, compare transfer gain with HSPICE reference tables and collect functional coverage. SystemVerilog assertions check supply current and bias voltage during power-down. The paper reports agreement within 2% of HSPICE for the illustrated filter example; this is not a general analog-model error bound. The official proceedings archive assigns the work to 2022; conflicting secondary citations to 2021 are not used to backdate the Event.
