Display more digits in Operating Point analysis

QSPICE

Hi,

How can I display more digits in the Operating Point data?

Why do you need more digits? 5 digits are not enough? How more digits will help you?

Yes, I need more than 5 digits, that is why I am asking. I want to corroborate analytic expressions with simulations, and I would like more precision. How many digits would help? as many as possible, although maybe not as many that the difference between the analytic and simulator results are below machine epsilon.

This might not be exactly what you want but try this:

Deselect “Fast (less accurate) Math:” if set.
This mode won’t allow you to select the digits of precision but may yield more precise results.

The way to get more digit from my experience is that

  1. Directly work on the .qraw binary file (I have a matlab project that can read .qraw in binary format)
  2. Command line batch mode to get a .qraw in ASCII format

This example is to run a file called digit.qsch in the folder C:\KSKelvinQspice\Temp
digit.qsch (1.1 KB)

Thank you. This seems to be the solution I was looking for.
