Display point to point rat nest for voltage nets

Jeff Underwood

My EE's have defined a lot of logical DC net voltages on our boards. Even though I don't use 'true' power planes, the guides for these nets appear as a square with an 'X' in the center of said square. Some of the many voltage nets will be connected on inner layers using areafills. However, a number of voltage nets will be routed as traces. How can I turn on the guides for those nets WITHOUT removing the assigned voltage on those nets?

    I would be surprised if this wasn't part of exporting and importing constraints from CM.

    Me do: Create a 'user defined' property for your voltages. Edit the nets and reset your VOLTAGE property to your new property. Then delete the VOLTAGE to get the ratsnest to appear. I don't know of another way around this, sorry.

    Hi Jeff,

    Adding the Net Property "RATSNEST_SCHEDULE" to the Voltage net with a value of "MIN_TREE" will replace the power unroute with a traditional unroute.

    Hope this helps,

    Awesome Mike! I looked for hours over the course of two days before I broke down and admitted defeat. This worked like a charm.... Cheers.....
