Import Cdl Netlist

hi, i want to import a Hspice netlist to cadence for automated place and route. in the cadence user's manual, it says that "import->cdl" can do such things. but it always fails when i do as it says in the manual. it produce a log file called nino.log, the information in it is as follow: (...)

When I import a cdl netlist in Cadence 5141, the VDD and VSS was convert to a general net in schematics. I hope they can be a VDD or VSS symbol. How to do this? Thanks a lot!

Yes,Composer also can import cdl to schematic. First you should modify you netlist to the cdl format(reference to the related document), and you shoule have a writable reference lib including the NMOSFET PMOSFET etc.

From the icfb File >>>> import >>>>>>cdl Fill out the form ensuring that the correct reference libraies are listed ie basic sample etc. It work for me! The only thing I dont have is the parmeter file. Try testing it on a very small schematic to start. "K"

You can import cdl into schematic first.

If you use cadence virtuoso, you can import cdl easily. As usually the device name and properties are different between cdl file and PDK, you need a map file when importing cdl. For details, refer to cdsdoc. Following is an example of the map file I used before. devMap := nfet n18 propMatch := subType (...)

hi, you can use "cdlin" in cadence virtuso File -> import -> cdl I am attaching one "Template File" and "Device-Mapping File". you have to edit the mapfile for your technology. Reference Library List -> your technology library contains the devices

I am trying to import some io cells for spectre simulation and am seeing some strange behavior. I have a map file that correctly identifies the devices and links them to the right pdk cells, however if a property is greater than 2 the following error appears in ni.err and the device is imported with a width of 0!! 65:MM2 Z A inh_vdde3v3 nwelle P

You can use the import cdl option in ICFB but you should modify the cdl netlist , MOSFT should be modify the subcircuit format .

Hi I am trying to import cdl to schematic in Cadence. I did get the schematic, but whenever the cell has more than 1 output, only one output is correctly converted, all other outputs are converted to inputs. For example, the following cdl netlist: .subckt ADDFHX1 CO S A B CI M0 net105 net123 net132 VDD P l=0.18u (...)

Hi, I have the netlist, how do I translate it to schematic? I tried 'import-cdl', the schematic library was set by 'samples/cdslib/sample'. It reports error: Failed to opent cellview (nfet symbol) from lib (/samples/cdslib/sample) in 'r' mode because cellview does not exist. Could anybody help me? Thanks.

Hi, I have a spice netlist file where in VCVS, CCCS are used. I wanted to import that netlist to cadence through import--> cdl... , I am able to see all the components in the resulting schematic except VCVS, CCCS. Is there anything special I should do for these components? Thanks in advance. Ramesh

Hi everyone, I have another problem, again... I have obtained a cdl netlist and a spice netlist from my verilog netlist. I used v2lvs to generate the cdl and SPICE netlist. Firstly I tried to import the cdl netlist into IC5. (...)

Dear, I'm not quite sure that this is the place to submit the question but any help is appreciated. Is there a way in virtuoso to import a netlist and create from this netlist a schematic? Thanks and best regards, S. 8)

it is possible you can import netlist using FILE->import in Cadence CIW I export an cdl of a schematic.then import it,however,it does not work. some setups are needed?

You import verilog netlist and then export cdl file, you can run LVS in dracula

cds_thru's may be due to assign statements in the netlist you imported. They may get converted into metal resistors in the cdl, or the cdl out may fail. That's is where I would check 1st.

Hi everyone, I'm trying to get Calibre LVS to work with digital standard cells, but I've hit a wall. Currently, DRC, LVS and PEX work properly with a full analog custom design created in icfb 5.1.41. However, if I do a LVS on a digital design that has only an inverter from the std cell library, I get a "nothing in layout" error. I get the same r

import the netlist which is from PR tool into the virtuoso to generate the schmatic of the design and then export the cdl netlist from the schmatic, it works better than use V2LVS, and you can avoid some problem

Hi Guys, Have anybody any experiences of using cdl import in DFII infrastructure? I want to import a flatterned hspice netlist into cadence design environment. But after I fill in the blanks in the dialogue of cdl in, the CIW showed that the process is successful. However, I do not see any added (...)

This is the thirdparty standard file format for netlist. For example, if you use leonardo spectrum to perform synthesis, once completed, you need to import the .edf file into quartus to perform place and route and get .sof file.

yes, it is possible to generate the schematics , but this method is a dirty fix. Calibre tool(from mentor) will have an utility call ver2lvs . it will convert verilog to lvs netlist or cdl. now you can readin / import this cdl into cadence virtuoso editor to get schematics. once serious drawback is your schematic will (...)

Have you tried to follow the Cadence's "Design Data Translator's Reference" "cdl import" chapter?
