Need Clarification for Rectangle symbol in allegro ??

kabalee

Hi everyone,

Let me explain any one what is this rectangle  ?? please clarify any one  ??

  • steve
    I'm assuming you mean the triangle (not the rectangle....) These indicate Diffpair driver pins. The control of the display is found under Setup - Design Parameters - Display tab "Diffpair driver pins".....

    thanks for your reply.but in my design i assigned differential pair in other location but triangle symbol is not visible.let me know why ??

  • steve
    It's how the diff pair has been defined. The driver pins are only shown on Model or Library defined diff pairs. It takes this info from an imported IBIS model. If you created these manually it won't show this info.
