RE: LC VCO startup issue for different transient algorithms
Hi Cherag, The gear methods (gear2 and gear2only) both end up applying a small amount of numerical damping, which can be deleterious to oscillation in oscillators. It's useful in other situations...

RE: How to get instance mode
I did both. opened the cell for edit and descended into the cell for edit. Same result instDb~>master~>mode = "r" Will check in it again

RE: How to get instance mode
Paul, Can you please post the results of the following, plus screenshots of the banners of the windows you've opened (the bit where it says Virtuoso Layout Suite ... Editing: lib cell view) - don't...

RE: How to get instance mode
instMode(CDB()) "zzz_psillaLib" "zzzCell" "layout" "a" ( I have to have the cell open for edit in another cell window to get an "a" for the mode; otherwise I get an "r" ) "zzz_psillaLib" "zzz_psilla"...

Transient PLL spur simulation setup
Hi, Officers, I have a question on how to accurate estimate the spur at PLL output by using transient simulation with DFT function in SpectreRF. For example, if the spur is located at 100 kHz offset...

RE: Transient PLL spur simulation setup
I don't think you've given enough information here. First of all the "DFT" function isn't anything to do with SpectreRF (it's a calculator function) and then you're talking about transient simulation....

RE: How to get instance mode
OK, so everything looks correct. That contradicts what you were saying earlier, where you said that even if you opened it for edit, the mode showed "r". I assume what you thought was that if you opened...

RE: Transient PLL spur simulation setup
Thanks, Andrew, To be more specific, I have two cases, one is that I am simulating a multi-phase (16 Phases) VCO at 2.4 GHz with reference frequency 40 MHz in integer mode, and by sequentially...

skill code for finding the pin which is not in the pitch
Hi, I have bunch of pins in the layout and suppose to be in the pitch, I have written skill code for finding the pin which is not in the pitch. My code is not working and I have observed that " if "...

RE: LC VCO startup issue for different transient algorithms
Thank you so much for the information Andrew. I completed the entire design without switching ON any algorithm (default setup). But when i thought to check with gear2/gear2only ( algorithm mostly used...

RE: skill code for finding the pin which is not in the pitch
Hi, I have had just a quick look at your code - one potential error is that you compare floating point numbers with '==': xCoord(car(sh~>bBox))==nth(i new_list) ...which might not do what you expect...

RE: Tests/Expressions/Plotting
Hi, 1) ADE-XL should be smart enough to use noise_ids from test_tr1 in noise_corner from test_tr1. Similarly for test_tr2. 2) The test names are not displayed in the legend. However, when plotting...
