Speeding Up Your Transient Noise Simulation in Spectre (Hint: Dyn Param : isnoisy)

When transient noise is enabled, the simulation runs much slower. My question is, since there may be startup phases that the circuit needs to go through to arrive at the state in which the transient noise analysis is useful, is it possible to tell spectre to introduce the transient noise starting at a specific time? For example, simulation runs till 10 us. Begin transient noise at 5 us.

Yes, you just use the Dynamic Parameter feature available in the Analyses form. Thank you Udit.



What about the Cadence Online Support Search and Gen AI not offering up this solution when one searches for "is it possible to introduce transient noise into spectre simulation starting from certain timepoint?" Ans: Till fixed, try different wordings. In this case, "how to introduce transient noise during specific time window" *does* serve up the solution

Plotting Device Parameters (gm, vdsat, etc) Vs Time or Temp

I feel like this has gotten more complicated. I think it might have been easier 10 years ago. Then again, I could be w. Go to resource: How to save and plot operating point parameters for Spectre simulator from ADE Explorer/Assembler In Explorer, you go to Outputs > To be Saved > Select OP Parameters Now, the schematic window is active and you can click on instances and each gets highlighted as you do. These get populated in the Assembler Outputs Setup You will see that the "Type" is not signal but oppoint. If you click on the Details field, it splits into two - the /whatever/deviceName is on the left, and on the new field on the right, you can enter parameters appropriate for that device, like vdsat, vth, cgs, etc.  The UI is very poor, but, on the right of this field is a button you can actually click to choose from a list. It'll even run a sim if necessary! If you want these plotted, you have to check the box to the right under the Plot column.

When You Want to Get Cycle-to-Cycle Jitter at PLL Output Due to the Reference Oscillator

Image
Caution - the script does not provide the correct result. You expect cycle-to-cycle to be a high-frequency phenomenon - and therefore, to not depend on the oscillator phase-noise or jitter. But the script will show a large value for c2c jitter on the PLL output. If you can figure it out, please post/comment. Designers Guide : Phase Noise and Jitter prediction , by Ken Kundert Converting Phase Noise to Cycle-to-Cycle Jitter in a PLL When designing or analyzing phase-locked loops (PLLs), one key metric of interest is the RMS cycle-to-cycle jitter at the output. Given phase noise data (typically in dBc/Hz) for the reference oscillator, how do we estimate the jitter after the PLL processes it? 🎯 Goal Estimate RMS cycle-to-cycle jitter (in seconds or picoseconds) at the output of a PLL , based on: Measured or simulated phase noise data (dBc/Hz vs. offset frequency) PLL dynamics: natural frequency ( fn ), damping ratio ( ζ ), divider ratio ( N ) Carrier frequency ( fc ) ...

HIdden States in Your Behavioral Model

Rewrite the module to remove the hidden state or if you confirm this hidden state will not affect the simulation result, you can ignore those hidden states in RF analysis by adding attribute 'ignore_hidden_state' before the module declaration. For example,  (* ignore_hidden_state *) module moduleA Yes, that's the exact syntax you need to use - that line works so much magic. It's strange that Cadence would offer behavioral models to customers in its ahdlLib library that aren't "ready to roll" in terms of NOT having hidden states. https://designers-guide.org/analysis/PLLnoise+jitter.pdf https://community.cadence.com/cadence_technology_forums/f/rf-design/26712/how-to-avoid-hidden-state-in-veriloga-model-for-spectrerf
