Hello all, I designed simple inverter using UMC65ll kit
and it passed successfully in DRC, LVS, and QRC. But extracted view of
this design isn't showing any metal layer instead schematic of
transistor is shown (figure attached). I have also ran QRC by setting
valid layers (LSW->edit->set valid layers->set all valid) but
problem still remains the same. Moreover, I am only using METAL1,
DIFFUSION and POLY1 layers. Versions are as follows.IC 614-06.14-512Assura 4.1 USR2 with EXT101 &MMSIM 0720.593How can I set up this to show layers in av_extracted view? Regards,
To see metal shapes in the extracted view is not necessarily requiredfor the function of the extracted view, storing devices, parameters, connectivity and parasitics.But the most likely reason if they do not appear is the missing "saveInterconnect"statement in your "extract.rul" file.
In reply to berndfi:
Thanks for your quick reply Berndfi. Ya view may not be required but once if we have an av_extract view then it becomes easy to trace out parasitics among layers for finding which layer is giving what value of prasitics.
I have included "saveInterconnect" in "extract.rul" file but still it's not showing any layers in av_extracted view. I have also attached my QRC log file here. Any other problem with this?
In reply to pavan7kumar:
In the "Create _save_layers" section of your log file there should be something like
"Copying Layer" or " Save recognition", which I can't see.
You got a bunch of warnings for "No library model" which I'm not sure where they are
related to, your "linbInti.il" or Assura?
Maybe you can try with "saveReconition" in the "extract.rul" file.
But my impression is that something goes wrong before it comes to writng the layers to the
I tried with "saveRecognition"but it doesnt work berndfi. In extract.rul I could only find "saveProperty" (in UMC65). But in GPDK180nm, I found lines such as
saveInterconnect((M6term "Metal6"))saveInterconnect((M5term "Metal5"))saveInterconnect((M4term "Metal4"))saveInterconnect((M3term "Metal3"))saveInterconnect((M2term "Metal2"))saveInterconnect((M1term "Metal1"))saveInterconnect((NSDterm "Nimp"))saveInterconnect((PSDterm "Pimp"))saveInterconnect((NWELLterm "Nwell"))saveInterconnect((CapMetal "CapMetal"))saveInterconnect((INDterm1 "INDdummy"))saveInterconnect((INDterm2 "INDdummy"))saveInterconnect((POLYterm "Poly"))saveInterconnect((JVARanode "JVAR1dummy"))saveInterconnect((Pwell "Pwell"))saveInterconnect((ISOPWELL "Nburied"))saveInterconnect((Nburied "Nburied"))
But i am not understanding how they mentioned layers and what it means to.
From library I have only used only tt_ll_rvt and it is not showing any warning about this. So i think this is not an issue.
>>But i am not understanding how they mentioned layers and what it means to.
Have you ever had a lookk into the documentation and tried to figure out how to apply
"saveInterconnect" or "saveRecognition" correct to your command rules.
