expression evaluation failed: waveVsWave(?x IDC("/V1/PLUS") ?y OP("/M0","ron")) - cadence virtuoso error

[mohamis288]

How can I solve this error in cadence virtuoso calculator?

expression evaluation failed: waveVsWave(?x IDC("/V1/PLUS") ?y OP("/M0","ron"))

I just want to show output resistance VS drain current when Drain-source voltage is constant.

1.
Split up the expression so it takes a few lines to carry out. Find which line generates the error message.

2.
Create variables as needed to hold individual results of calculations. Example:
* value of "/V1/PLUS"
* value of IDC("/V1/PLUS")
* value of OP("/M0","ron")

3.
Create a single variable for the X axis, and a single variable for the Y axis. Make things simple as possible for the software.

4.
Try to reduce amount of quotes on each line.
Try to reduce amount of parentheses on each line. Minimize all opportunity for syntax errors.
