Dears I am trying to do calibre extraction for inverter but i am facing this problem ERROR: Could not find cell mapping for device nch. Ignoring instance M0. ERROR: Could not find cell mapping for device pch. Ignoring instance M1. However the LVS passed successfully, could you please help me in that. I am using TSMC65n
Hello All, I designed a layout in SoC Encounter using NangateOpenCellLibrary 45nm which had zero geometry and connectivity violations. I then exported GDS file and verilog netlist from Encounter. I went to calibre to run LVS and afterwards PEX for post-layout simulations. Here are my steps: 1) run v2lvs command "v2lvs -v (...)

That could be it. When you say there were zero geometry and connectivity violations in Encounter, are you sure you ran the checks at the top level? For the calibre issues, it is odd to have over 12,000 ports in the layout, and also odd that the top level port names are not valid for netlisting. These hint at a problem in the layer mapping. You m
I'd need more details to recommend the best way (see the section "Best Way to Resize Designs" in the xrc_user manual) but you could try adding "layout USE DATABASE PRECISION YES" to the SVRF rule file. (That is supposed to be the default for xRC and xL if it isn't specified in the rule file. It is possible the foundry has reasons for wanting you t
SPF and DSPF stand for the same thing - its an acronym for "Detailed Standard Parasitic Format". DSPF (or SPF) file is the output of extraction tool (StarRC, QRC/Quantus, calibrePEX / XRC, F3D,...) - a text file containing post-layout netlist. It contains information about design elements (MOSFETs, diodes, BJTs, resistors, capacitors, inductors,...
Hi guys! When i copy the layout of the triple well mosfet nfet33tw from the pdk (ibm 130nm) as it is and ran lvs on this single device without any modification or connections, the calibre is unable to recognize the device. Am i missing anything here? Thanks
Hi Guys, I'm developing layouts circuits using FreePdk45nm and the NCSU just released DRC rules checker to calibre.. Is there any free version of the software or any option to analyse the errors? Thanks in advance!!
I was error "missing port VDD,GND,IN,OUT" in process layout lvs calibre cadence I need help Thank all 134050134051
This is a standard DSPF (Detailed Standard Parasitic Format) file format. It is usually generated by extraction tools (StarRC, QRC, calibre PEX, F3D, etc.), and contains parasitic elements (R, C, L. K,...) and design elements/instances (transistors, capacitors, etc.) along with their layout-dependent parameters. DSPF (also sometimes called SPF) fi
Hello all, I am currently working on layout in cadence virtuoso having calibre tool. In inverter while doing DRC,I am getting the following error which I am unable to solve since 1 month and I didn't found in google. 1. Offgrid error 2. Orthogonal corners are not allowed at die edge. 3. related to M1,M2,GC coverage. (GC coverage less than 0.2
I was using cadence virtuoso for my entire career(last 10 years) and never worked in any mentor layout tool(except calibre verification) Now my new project is going to start in Mentor Pyxis, I am not at all familiar with this tool. I am feeling very difficult in doing layout and modifying layout with this tool, is there is (...)
Hi everbody, I have Installed IC610, MMSIM12, Assura and calibre 4.12 x86_cal_2011.2_34.26 ON the Ubuntu 10.04 32 'bit the OS. I got a problem with calibre interactive below, 127577 *** calibre Interactive: Exporting layout for library "tsmc18rf", cell "transistor", view "layout" *** sh: pipo: (...)
This is perhaps too basic, but... is IC6 set to export the layout to calibre? Is the pcell listed in an LVS Box statement as something to be ignored?
Hi, I am using clibre for pex. I want to avoid double extraction of rf models e.g. nfet_rf I have declared xcell file as follows: nfet_rf* nfet_rf The problem is when I use Outputs>Get net names from schematic, this does not work and double extraction happens. When I use get names from layout, it works but my cellmap gives me error and
hi guys, anyone can help me between calibre and hercules using their option?? in calibre, can use 'layout POLYGON' option.. but in Hercules i can find out how to using like calibre... i saw manual and ask other people, found some of hercules option.. : POLYGON_FEATURES and RECTANGLES. but is was not same like (...)
Dear All i have design a transconductance amplifier. done with layout of it.. cleared DRC and LVS and PEX. in PEX i m getting some warning. i m not able to understand those warning but because of these warning i m able to generate config view. i m attaching the error file
I see there is a "blank" between inverterlayout. & calibre.gds Guess calibre cannot cope with blanks in file_names.
Hello all, I have a strange problem running DRC check using calibre. When I start Virtuoso, license "111" is succesfully checked out and everything works fine (Schematic, layout, MMSIM). I implemented the calibre skill interface in the .cdsinit and the drop down menu in layout editor appears. When I start (...)
Hello, Is seems like your extraction tool use real capacitor and resistors instead of pcapacitor and presistor. But I don't shure with it. Do you have other extraction tools? Assura or calibre maybe...
