user defined parameter in dynamic parameter transient simulation

Found solution. My Apologies

Please reply to your own post rather than editing it later. Otherwise I just spent a few minutes setting up a testcase and searching to see if this was a known issue when (as I expected) I couldn't reproduce it and was going to ask for more information - and now I find that you've edited the post and I just wasted time. It helps others to have a problem description and a description of how you solved it, even if you solved it yourself. As it is, this post now adds nothing to the sum of human knowledge and has wasted some of my time on New Year's Eve...

Original Post -

I am trying to run Transient Analysis with Dynamic parameter setting . In Analysis, Running DC OP, Transient Analysis with Dynamic parameter enabled. I am  using param= user-defined  "temp_cal" and It is also defined as  variable as design variable.

Parameter file include following setting-

; comment - time scale mS
tscale = 1e-3
time value
0 0
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9
10 10
11 11
12 12
13 13
14 14
15 15

I am unable to run transient analysis and There are following errors -

Error found by spectre during DC analysis `dcOp'.
ERROR (SPECTRE-16654): There is no equation in the netlist.

Analysis `dcOp' was terminated prematurely due to an error.
dcOpInfo: writing operating point information to rawfile.

Opening the PSF file ../psf/dcOpInfo.info ...

Error found by spectre during DC analysis, during info `dcOpInfo'.
ERROR (SPECTRE-16041): The `dcOpInfo' analysis is skipped due to inability to compute operating point. Run 'mmsimpack' (see mmsimpack -h for detailed usage information) to package the netlist and log files as a compressed tar file. Then, contact your Cadence representative or submit a service request via Cadence Online Support, including the tar file and any other information that could help identify the problem.

Analysis `dcOpInfo' was terminated prematurely due to an error.

Solution -

I have found out that This error were due to DC analysis and There is no issue with  Transient Analysis with dynamic parameter. As I was using copied test bench setting. so, used fresh test bench with all required inputs and error were resolved.  I am not sure what is reason behind  dcOP error.
