Hi Subgold,
As far as I know, The awd defaults can only be customized using the Skill function "awvSetOptionValue". Therefore, you need to make use of the .cdsinit file, not the .cdsenv as the latter does not understand Skill. the .cdsenv file reads the direct tool customization without any sort of evaluation.
For your particular question, you may try the following in your .cdsinit file:
Code:awvSetWaveformToolName("awd")
awvSetOptionValue("numIdentifier" 50) ; 50 ticks
Please note the need to set up awd as the the waveform viewer as default is wavescan, assuming IC5141.
Also, you can use awvSetOptionValue() anytime during the run of your cadence session as any changes take effect at the next started awd.
All of the above is documented in the "Virtuoso Analog Design Environment SKILL Language Reference" that is available through cdsdoc/cdnshelp in your IC/doc install.
Cheers,
Riad.
