Strengths of <strong>Spectre</strong><strong>RF</strong> <strong>Noise</strong> aware <strong>PLL</strong> flow<br />
Significantly decreases simulation time compared to a<br />
traditional spice/fast spice transient approach:<br />
–<br />
–<br />
Even simple <strong>PLL</strong>s can require 2-3weeks when simulating with<br />
traditional SPICE simulators.<br />
Complex <strong>PLL</strong>s can easily require 2-3 months.<br />
Provides accuracy comparable to a traditional spice<br />
transient approach:<br />
–<br />
The VCO dynamic behavior is fully captured by using a non<br />
linear model based on PPV.<br />
Supports both Integer-N and Fractional <strong>PLL</strong>s<br />
