Title: ncelab error - verilog functional instance unresol Post by raftman on Aug 29th, 2006, 1:28pm I am having issues elaborating my design in AMS. The ncelab log file is as follows: ncelab: 05.40-p004: (c) Copyright 1995-2004 Cadence Design Systems, Inc. ncelab: *W,DLCILIB: Library name 'my_lib' not found, defaulting to 'MY_lib'. Please see nchelp on this error. ncelab: *W,CUNOUN: Cannot find any unit under MY_lib.my_cell:functional in the design libraries. ncelab: *E,CUCFUN: instance 'I28' of the unit 'my_cell' is unresolved in 'MY_lib.my_test_cell:schematic'. I am concerned with the CUNOUN and CUCFUN warning/error. (I think the DLCILIB warning is just because my library has capital characters in it) I have tried explicitly netlisting my_schematic via CIW->tools->AMS->netlist, but this does not help. The ncelab help manual says the following about the error: ncelab/CUCFUN = The specified instance in the named module could not be resolved using the 5.x configuration specification available. I have no idea what the '5.x configuration specification' is. thanks for your help!!! |

Have you netlisted THAT schematic? if its a primitive device did you setup your model files? does the PDK for it have an ams view, and amssiminfo ?? Jbd |
Title: Re: ncelab error - verilog functional instance unr Post by raftman on Aug 30th, 2006, 7:05am The instance I28 is an imported verilog functional block. It only has functional and symbol views. I wrote the verilog externally and imported it to cadence via CIW->file>import->verilog This schematic simulated using spectreVerilog, so I'm not sure how to proceed. I thought AMS would compile the verilog when I compiled the toplevel testbench cell. Thanks! |

I don't see the need to "IMPORT" it except to get the symbol.. but when you look at the HED, do you have "functional" view in your switch list? SpectreVerilog uses Verilog-XL.. maybe there is an incompatibilty with Verilog-2001 so that the model doesn't compile properly with ncvlog? Its not quite the same Verilog!! jonathan |
Title: Re: ncelab error - verilog functional instance unr Post by jimwest on Apr 11th, 2008, 11:37pm I met with the same problem in ams elabrating. I don't think it a compatible issue, cuz the simulation would be smooth if I had not changed the certain block. But I still cannot find the way to overcome this error |
