CIC 1.SpectreRF Overview
CIC. 1. SpectreRF Overview SpectreRF is an optional feature added to Spectre ,and is represented by 6 analyses: 1. PSS: Periodic Steady State Analysis 2. PAC: Periodic AC Analysis 3. PXF: Periodic Transfer Function Analysis 4. PNOISE: Periodic Noise Analysis Tdnoise: Time Domain Noise QPNOISE: Quasi-Periodic Noise (not discuss here). 5. PDISTO: Periodic Distortion Analysis QPSS: Quasi-Periodic Steady State (not discuss here). 6. Envelope Analysis (not discuss here). PAC, PXF, and PNOISE are similar in concept to AC, XF, and Noise. However, they are applied to periodically-driven circuits such as mixers and oscillators. 1-1. CIC. SpectreRF in a Design Flow Design Schematic Analog Artist Environment Models The netlists include all components along with an analysis selection, simulation Netlist controls and statements to save, plot nodes or currents. SPECTRE Engine Spectre RF Control Analog Artist Plot Results Use Direct plot or the Calculator plot capabilities. 1-2. CIC. SpectreRF Tool Flow SpectreRF.
