region and reversed in transient results

syafiq

Hello,

I was looking at the transient results (using result browser), I saw two parameters which are region and reversed.

I belief region is referring to operating region of the MOS transistor as below. But I need a confirmation from you guys if this is correct?

region = 0 : cut off

region = 1 : linear

region = 2 : saturation

region = 3 : sub-threshold

region = 4 : breakdown

Another thing which I completely unsure is reversed. What does it mean actually by this parameter? It got number assigned into it.

example: reversed = 0. Could you help to explain what is 'reversed' and what the meaning of the number?

Thanks

  • Hello Andrew,

    I got one more concern. I ran dc simulation to know my circuits operating region. Basically you can load the raw file into result browser and go to dcOpInfo to check the region of transistor.  But I got quite a lot of transistor =256 transistors.  My I know how to extract the region for every single transistor?

    And another question what is the difference between Id and Ids? I thought both are the same which is referring to the drain current of the MOS transistor, but sometime it gave same value, sometime NOT.

    Thanks
