Hi,

can I create in Altium Designer a rule like this Length rule in the pdf-File, please search it am1808.pdf with google because it's not allowed for me to post links, on page 119 No.1

under the table 6-36 there is a note:
CKB0B1 is the sum of the length of the CK net plus the average length of the DQS0 and DQS1 nets.

I don't know if it's possible because in the PCB Rules and Constraints there are only the two rules i know like Length and Matched Net Length Rules.

Thanks and Regards,

Andreas

It is possible but you have to really try out on DRC settings.
I think using adnvanced query option in Altium you can define the particular setting.

I think the only problem I have to figure out how I can form the sum. Does anyone have a syntax proposal.

Thanks and Regards,

Andreas

i think help document named "Tuning Route Lengths" could help you in setting up the rule.

Also you can go through this thread

i think you can do it with 'query helper'. check these pdfs; AR0129, TR0116 and 'TR0110'.
