Interpreting UPF For A Mixed-Signal Design Under Test


This paper describes a methodology (as implemented in the Mentor Graphics Questa ADMS mixed-signal simulator) for interpreting the Unified Power Format (UPF) for analog mixed-signal designs coded in Verilog-AMS, VHDL-AMS, or SPICE. No changes to the UPF syntax or file are required. A complete implementation and a demonstration of its use in a sample case are provided as proof of concept. To ... » read more

The New Mixed-Signal Flow


By Ann Steffora Mutschler We are on the cusp of the mixed-signal era. Traditional mixed-signal design environments, in which analog and digital parts are implemented separately, no longer are sufficient. They lead to excess iteration and prolonged design cycle time. Today’s mixed-signal designs require a new approach that enables design teams to be as efficient as possible productivity... » read more

The Double Whammy


By Ann Steffora Mutschler Given that at 40nm and below every [getkc id="81" kc_name="SoC"] has some mixed-signal content, combined with the fact that power awareness is top priority no matter what the target application is, design teams and verification engineers are grappling with tremendous challenges just to get a chip to yield. “For verification engineers and for designers, this is a ... » read more
