Check out how to model a precharge-type phase-only detector (PD), which is suitable for aligning two clocks with a zero phase offset in a DLL. This PD was first published by S. Sidiropoulos, et al. in 2000.
Learn the various options available for the dump primitive or $xmodel_dumpvars() command to dump just the waveforms of specific signals or signals contained in specific instances only.
This primitive converts an xbit-type input to an xreal-type output, of which logic-1 and logic-0 levels can be varied with the level1 and level0 input signals.
This release adds many improvements and bug fixes including the improved speed of the stline primitive and the --select option for the sparam_to_tline utility to support partial selection of ports.
