Forum Post: RE: Time log

In the Status Form (Display > Status) there is a Statistics section which records the time the database has been opened and updates the number when the design is saved. It does not keep track of of...

Forum Post: RE: Time log

That's where it was hiding. Thanks so very much. I thought I needed to setup an NTP time service option and point it to a Sever in the File Properties dialog box. I just could not get that to work.......

Forum Post: RE: How to short a net and a shape on layout using VIA

Hi On your schematic you have three nets, VSS, AGND, PGND. Are you wanting to short VSS and AGND to the PGND Shape with vias on the board using the net_short property. Perhaps I am reading this wrong...

Forum Post: RE: How to short a net and a shape on layout using VIA

Hello Paul, The final goal is to short VSS and AGND to PGND. However, in the picture both VIA are connected to AGND. I would expect that once net_short has been set on both they should be connected...

Forum Post: Queue list in job policies of ADE

Hello All, Under the job setup in ADE, there is a drop down under "queues" where I can select the available LSF queues. Earlier I was able to see "normal , regress, hwsim" . Now only normal is showing...

Forum Post: RE: How to short a net and a shape on layout using VIA

Quite hard to tell exactly what is going on from just a screenshot but possible issues could be: Shapes are Dynamic and not up to date, check Shape>Global Dynamic Parameters or Design Status; the...

Forum Post: RE: Inter Layer Checks - Same Subclass to Subclass?

I don't think it's possible unless you have access to Ravel and you can write a custom DRC. You may also be able to do this with skill. Good reason to be able to do it though so file and enhancement...

Forum Post: Number of accepted tran steps in spectre log

When a transient analysis in spectre is done, in the log file there is a statement " Number of accepted tran steps" . And it shows a big number. However in the statements above, a very few number of...

Forum Post: RE: How to short a net and a shape on layout using VIA

Hi oldmouldy and thanks for your reply. PGND shape is dynamic. Indeed you can see that the vias are completely surrounded by it (because of the NET_SHORT property on the VIA)rather than having the...

Forum Post: RE: Allegro Replicate

Replication method not useful here, like for me. You have to invent your own way of project. At legit website of Allegro you can read documentation.

Forum Post: variable $freq in veriloga

Can use $freq in veriloga if I want to create an expression for say a frequency dependent gain in AC analysis? I gave this a try but so far it hasn't worked but the veriloga compiler and the spectre...

Forum Post: RE: variable $freq in veriloga

Robin, There's limited support for this - from MMSIM15.1 ISR3 onwards. Not sure what version you're using. I think it's a bit fussy as to what works and what doesn't. My initial attempts didn't work,...

Forum Post: RE: Set a permute rule with SKILL

Yes. Depends on what is in the CDF already. If the auLvs simInfo exists already, it would be: cdf=cdfGetBaseCellCDF(ddGetObj("gpdk045" "nmos1v")) cdf->simInfo->auLvs->permuteRule="(p D S)" If...

Forum Post: RE: PSS issue when enabling APS multicore simulation

Sounds a bit odd - but I don't think I could diagnose this without seeing more of the setup information. Could you at least post the bottom part of the input.scs - with all the options and analysis...

Forum Post: RE: Number of accepted tran steps in spectre log

This is controlled by the transient "annotate" option. It's set in ADE to be "status" which gives you a regular update on the progress of simulation and uses some heuristics to let you know when it's...
