I have a problem
with CADENCE, importing or creating a VERILOG-AMS file.
I have to import a device model which has been developed in Verilog-AMS (I have a file with ".vams" extension).
In the following, I try to summarize and explain what I have done and tried.
1)
I tried to import my file through the "IMPORT" tool of CADENCE
but it seems to be impossible. I have this error: "The parser ncvlog failed to parse the text file. Refer to the file 'ncvlog.log' for compilation messages and errors". I don't know if the problem is related to the verilog editor/compiler named "ncvlog".
2)
I tried to use the tool "NC-VERILOG". Also in this case, when I try to
generate the netlist from the "verilog-ams" file, I have the
following error:"ERROR
(OSSHNL-103): Unable to open the design, library 'GMR_Model', cell 'Test_2', view 'verilogams'. Ensure that the cell view exists or the
SKILL variable, simDcmFilePath, is correctly defined".
3)
I tried to generate a new cell view creating a "Verilog-AMS" file with the "modelwriter" of
Cadence or creating a "VerilogAMSText" utilizing a Verilog-AMS editor of
Cadence.
Once again I have problems because, in the first case, the
ModelWriter of Cadence works fine but it is possible to create "verilog-ams" files only starting from a list of examples, without any
possibility to change something. The
generated example can be simulated with good results. On the contrary, when I try to generate a new "VerilogAMSText" utilizing a Verilog-AMS editor, a file "verilog-ams" is created, but not opened
automatically with the editor. I have this warning: *WARNING* editFile: sh: xterm: command not found.
I
tried to set (manually) the editor for "verilog-ams" utilizing this
command: "editor=<PATH of the editor>". I checked both "EXTERM"
and "ncvlog". In the first case, setting: editor="/ic_tools/cds/IC.6.15.011/tools.lnx86/dracula/bin/32bit/EXTERM",
when I try to generate a new file, the window of editor does not
appears (probably the Editor doesn't work) and I have this error:/ic_tools/cds/IC.6.15.011/tools.lnx86/dracula/bin/32bit/EXTERM:
error while loading shared libraries: libgdbm.so.2: cannot open shared
object file: No such file or directory. In the second case, setting: editor="/ic_tools/cds/IC.6.15.011/tools.lnx86/inca/bin/ncvlog",
when I try to generate a new file, the window of editor does not
appears (probably the Editor doesn't work) and I have no errors. However,
in both cases, a file "verilog-ams" is created in the "view" column and
it is only possible to open it in "read-only" modality. In this case,
the file is opened through a windows of VerilogAMS-Editor without any possibility to modify/edit the file and run the compiler VerilogAMS.
Where is the problem? Is it related to Linux, the installation of CADENCE or other?
How can I do to create a Verilog-AMS view and then simulate it?
Thanks a lot.
