Tip of the Week: Guidelines for getting accurate HB QPSS/QPNoise results

Tawna — Fri, 09 Jan 2009 14:00:00 GMT

Two of the most important parameters for accuracy are: (1) maxharms (2) oversample maxharms: The accuracy of HB is greatly dependent on the number of harmonics chosen. As a general rule, you should simulate with with maxharms [5 3] and (if memory allows...(read more)

How to Simulate a Subcircuit (Netlist) With Spectre in ADE

Tawna — Wed, 07 Jan 2009 21:00:00 GMT

Many users ask, "How do I instantiate a netlist into my schematic and simulate with spectre in ADE?" To instantiate a subcircuit (netlist) in your schematic and simulate with spectre in ADE you need to create a cell with a CDF parameter 'model'...(read more)
