Last year, I wrote a blog post entitled Modeling Oscillators with Arbitrary Phase Noise Profiles . We now have an easier way to do this. Starting in MMSIM 13.1 , you can specify the phase noise as an instance parameter in Spectre sources, including...(read more)

Hello Spectre Users, Simulating S-parameters in a time domain (transient, periodic steady state) simulator has been and continues to be a challenge for many analog and RF designers. I'm often asked: What is required in order to achieve accurate...(read more)

Hi All, If you were unable to attend IMS 2017 in June 2017, the IMS MicroApp “7 Habits of Highly Successful S-Parameters” is on our Cadence website. On Cadence Online Support , the in-depth AppNote is here: 20466646 . Best regards, Tawna...(read more)

Large-signal S-parameters (LSSPs) are an extension of small-signal S-parameters and are defined as the ratio of reflected (or transmitted) waves to incident waves. (read more)

When I place a pcell and do not change the W parameter (default is used) the value is not saved in the OA cell property.

When I change the default value of the super master now, the old pcell will get the new default value automatically because there is nothing saved inside the OA cell for this parameter.

Do you have any Idea, that how we can save the default values in the OA cell properties so that this value doesn't get updated if the default values are updated in the new PDKs

Hi all,

I want to write a script SKILL to create the title & frame for view schematic. My question is whether SKILL supports any function for me to do this.

Hello, I am trying to use two inductors in my LNA as shown bellow to have a S-PARAM response so i will have S11 with lowerst possible values and tweak them for matching network. However when i ran EXPLORER live tuning with SParam as shown bellow i get no change in the response.

I know that Cgs and Cgd with the inductors having a resonance so by Varying L value i should have seen the change in resonance location,

But there is no change.Where did i go wrong?

Thanks. 

Hello, i need to test the  parameter Kf under some conditions in subthreshold.i cannot just plot the OP param,becasue i need to derive it under certain conditions.

Spectre(of Cadence) like BSIM(of Berkley) has developed a method for deriving each parameter in their model.

Is there a way to help me with such manual where i can test in cadence virtuoso the Kf parameter shown in the formula bellow?

Thanks.

Hi,

I wanted to find the location of a pin in the design using skill program. pin_dbids = axlDBGetDesign()->pins, this gives me all the dbids of the pins that are present in my design. But when im entering that dbid, pad = axlDBGetPad("000001EA8FD8B9F8" "package geometry/assembly_top" "regular") it is throwing an error stating "This dbid is not user defined. Please enter the user defined". So please provide me a snippet so that I can get the exact pin location in the design using skill script.

Hi all,

I am using ADE assembler.

I ran transient simulation and swept the input frequency (Fin) of the circuit. And I use Spectrum Measurement to return a value of the fundamental tone magnitude (Sig_fund) for each sweep point. 

Previously, I use "plot across design points" to plot both "Fin" and "Sig_fund", and then use "Y vs Y" to get a waveform of Sig_fund vs Fin. Measure the 1dB Bandwidth with markers. 

Can I realized above measurement with an expression in "output setup" ? And how?

I know to set the "Eval type" to "sweep" to process the data across sweep points. But here, it has to return an interpolated value from "Fin" with a criteria "(value(calcVal("Sig_fund"  0) - 1)". I am not sure whether it can be done in ADE assembler.

Thanks and regards,

Yutao

Before I ask this, I am aware that I can output an s-parameter file from an SP analysis.

I'm wondering if there is a simple way of creating an s-parameter model of a component.

As an example, if I have an S-parameter model that has 200 ports and 150 of those ports are to be connected to passive components and the remaining 50 ports are to be connected to active components, I can simplify the model by connecting the 150 passive components, running an SP analysis, and generating a 50 port S-parameter file.

The problem is that this is cumbersome. You've got to wire up 50 PORT components and then after generating the s50p file, create a new cellview with an nport component and connect the 50 ports with 50 new pins.

Wiring up all of those port components takes quite a lot of time to do, especially as the "choosing analyses" form adds arrays in reverse (e.g. if you click on an array of PORT components called X<0:2> it will add X<2>, X<1>, X<0> instead of in ascending order) so you have to add all of them to the analyses form manually.

Is any way of taking a schematic and running some magic "generate S-Parameter cellview from schematic cellview"  function that automates the whole process?
