cadence auto save

In the process of usage,
1: I find that when i use the function display device DC operating piont. The result is too long displaying beside the MOS (about 20 digitals) how can change it into 6 effective digital.
2: I'm using SPECTRE as simulation tool, how could i make cadence autosave the results everytime i run it. so if i want to see the result i just select one of the results and plot it.
thanks a lot!!!
 

autosave in cadence

1. Instead of printing the op on the schematic itself, you can get it to print it in a new text window.
2. In ADE -> Outputs -> Save All -> select the relevant bits you want to save.
 

i tried it.
i can't find the option of select the relevant bits you want to save.
by the way, i use the version 5141.
any other suggestion?
thank u all the same.
 

1. Results>Print>DC Operating Points, click on the device. In new window go to Expressions>Display Info and set Number of Significant Digits.
2. if you want to plot nets you can do Results>Direct Plot and choose according to the simulation you performed then click on the net. For terminals you have to do Outputs>Save All and choose the appropriate option. Type spectre -h save in terminal for help on saving signals.

oermens! you are so kind.
thank u so much.
Problem 1 is sloved via the way u told me.
As to the problem 2, I followed your instruction to key in spectre -h in terminal.
then i found many useful commands. One of them is " +savestate" :that means turn on savestate capability. so i typed in command "spectre +ss" it said: will not read net list from a terminal. then i found the command is defaulted from environment variables 'spectre_DEFAULTS'or'SPECTRE_DEFAULTS', I opened my source file, and cannot find it does not include variables of 'spectre_DEFAULTS' or 'SPECTRE_DEFAULTS'.
Where can i find variables of 'spectre_DEFAULTS' or 'SPECTRE_DEFAULTS'?
am i taking the right step?
I just want spectre to autosave the results everytime i run it.
thanks a lot!
 

hey everybody.
I found the solution finally!!!!

This .cdsinit setting should do it:

asimenv.misc numberOfSavedRuns int 10

or from SKILL:

envSetVal("asimenv.misc" "numberOfSavedRuns" 'int 10)

It's covered in the <instdir>/doc/anasimhelp/anasimhelp.pdf

That is really. Wish that be helpful for people who encounter the same problem.
