Cadence/Virtuoso: Error found by spectre during circuit read-in.

[Dr. von Rosenstein]

Hi,

I have a testbench-schematic for an rectifier:


If I start Cadence and open this schematic and ADE GXL with the related adexl view and I run the simulation everything is alright. But if I subsequently "Check and Save" this schematic without any changes in the schematic and after that I klick "Run Simulation" again, then the simulation fails and in the output log I can read:

Warning from spectre in `ideal_balun', during circuit read-in.
WARNING (SFE-618): "input.scs" 190: Unterminated subcircuit. Terminating statement at the end of file.
.
.
.
Error found by spectre during circuit read-in.
ERROR (SFE-3): "input.scs" 190: `ideal_balun' is being redefined. It was defined at `input.scs' 77 before. Remove or rename either of them.

If I close ADE and reopen it, the simulation runs again without any problems.

In the input.scs the lines 74-81 are:
// Library name: analogLib
// Cell name: ideal_balun
// View name: schematic
subckt ideal_balun d c p n
K0 (d 0 p c) transformer n1=2
K1 (d 0 c n) transformer n1=2
ends ideal_balun
// End of subcircuit definition.

And the lines 187-190:
// Library name: analogLib
// Cell name: ideal_balun
// View name: schematic
subckt ideal_balun d c p n

Could anyone explain what I'm doing wrong?

Thank you!

Delete or comment line 190

I forgot to say, that this file is located in the following two folders(for example):
/scratch/x09/lischer/IC615/analog_Frontend/Test_Rectifier/adexl/results/data/Interactive.316/1/analog_Frontend:Test_Rectifier:1/netlist
/scratch/x09/lischer/IC615/analog_Frontend/Test_Rectifier/adexl/results/data/Interactive.316/psf/analog_Frontend:Test_Rectifier:1/netlist

I tried to comment line 190 in both files. But the next time I start a simulation these files are recreated in the folder
.../Interactive.317/...
(for this example) and in the new input.scs files line 190 is uncommented and I get this error again.

The problem is more and more curious. I have another schematic in which last week was an ideal_balun. But now there is only a PORT, GND and a varactor. As with the other schematic, the simulation runs after I opened the schematic and ADE. But if I check and save the schematic the simulation did not run and in the log I can read:

Warning from spectre in `ideal_balun', during circuit read-in.
WARNING (SFE-618): "input.scs" 76: Unterminated subcircuit. Terminating statement at the end of file.

.
Error found by spectre during initial setup.
ERROR (SPECTRE-4080): There are no components in the circuit.

After closing and reopen ADE the simulation runs without problems.
