Hello,
I am using Cadence Virtuoso version IC6.1.8-64b.500.6
I have designed a frequency output temperature sensor. I have formulated the sensor sensitivity s(f) over corners, which is yet only the temperature, the basic idea is to monitor the sensitivity change with T which helps me to investigate the sensor linearity.
I used the ADE assembler to enter the sensitivity expression, which simply df/dT, where I used the Cadence calculator to calculate it using the "deriv" function. I have selected "all" from the EvalType.
Until this point there is no problem, I run the simulation and cadence presented me correctly the sensitivity over corners as shown in the picture below:
Then later I wanted to do more calculation over it by sending it to the calculator, for example applying average or whatever function. The data type in the calculator looks like as shown below
And I recived the following error after applying my averag function to the signal as shown below
Thank you for your help in advance
Regards
