Is there a way to set the `default_nettype directive through the command-line...
For instance, something like: irun top.v -f manifest.f +define+FPGA=1 +default_nettype=none As opposed to putting: `default_nettype none Within the files themselves. Either a direct way or a workaround...

RE: Verilog A ADC design
Well, the first problem is that with an input signal of 4GHz and a clock frequency of 800MHz, your signal is undersampled (i.e. above Nyquist) and so you'd expect a DC output since the input signal is...

RE: Verilog A ADC design
Thanks Andrew for your descriptive reply. To be very specific I am using this ADC in the front end for data acquisition in Compressive sampling. For my final year thesis ( I am an undergrad student in...

ADE Explorer Real time tuning with schematic DC annotations
When you run a DC analysis you can annotate the voltages and currents on the schematic. Is there any way to use this with ADE Explorer's real time tuning? ADE Explorer won't let the mode run without an...

RE: Verilog A ADC design
Given that I'm not realistically going to study a 60-odd page thesis to answer a question on the forums (you have to do something for your degree!) I merely quickly scanned it. The system is a...

RE: ADE Explorer Real time tuning with schematic DC annotations
Matthew, Which subversion are you using? You're right that an output is needed (I just added an output expression of VDC("/out") for example and that was sufficient). I can then go into Real Time...

RE: Spectre simulation of verilogA file
Hi Andrew, Thanks for the quick reply. I tried a few things to try resolve the issue without success. I cleared most of the disk space (pretty much with just my verilogA, schematic, spectre files...

RE: SKILL for changing via.
Regarding to your 1) and 2) point below code works for changing via without deleting the vias, as you told. procedure(viachange2() cvId= geGetEditCellView() vias = geGetSelSet() leReplace(cvId vias...

RE: SKILL for changing via.
This does delete the via and add it again. It's just using a higher level layout editor function (rather than a db function) to do it. Unfortunately all it does is preserve all the other attributes on...

RE: Spectre simulation of verilogA file
Changing the umask to 0 is unlikely to help as that only adds "other" write permission; you should already have write permission for you as the user (and your group, given that your umask was 002...

RE: Liberate_AMS for .lib generation.
Liberate has this variable, spectre_use_char_opt_license, which is a common setting for all Liberate tools. By default it is "1", ie. "on". You can use set_var spectre_use_char_opt_license 0 to turn...

RE: Spectre simulation of verilogA file
It worked! I could not help smiling when it compiled. I set it to 64 bit in my ADE and it worked. So I guess that 32-bit spectre was the issue. Thanks a lot Andrew! Krishnaa

In Other News, 100 People Were Killed by Cars Driven by People
You probably heard that last week, a woman was killed in Phoenix by a driverless car. In 2016, 37,461 people were killed on US roads. So if that day was typical (and it probably varies by weekday...

RE: Save and Recreate TrackPattern
Hi Markus, Unfortunately SKILL support for the Advanced Node features of Track Patterns is a bit lacking (there are a handful of functions, but nothing that returns the width). In general we'd say that...

Hi Andrew, The instructions in your first paragraph got it working. I think it was as you said: I hadn't explicitly run an initial simulation and was just moving the slider about for no reason. Many...
