Can anyone help me as how to assign differential pair in allegro 15.7.......i tried by opening setup tab but in tat i wont find Electrical constraint option to set ECSets.
I have checked in that logic tab but in that tab i have only 3 options i.e,identify DC nets,assign Resdes,auto rename refdes and i dint find assign differential pair option
I am using 15.7 .
1.select SETUP--> electrical constrain set (picture1)
2. select NET --> differential pair
3. select the nets simultaneously (using CTRL key )you need differential property (picture2)
4. Right click --> create -->differential pair
5. there you will get a window where you can name the differential pair (default name is DP*)
6. click on create. Now differential pair is created.
7. new DP1 pair will come on the Top of the all net names ( picture3)
8 . There assign set values like 'primary gap and primary width' etc
9. now in PCB you can route differentially ( it will route as a pair when you route a single net).
