Negative source current values reported in vc results

Rajesh Vembu
Rajesh Vembu over 14 years ago
I'm seeing some violations in the vc results, during SIRD analysis using EPS 9.1, as all the source currents are reported in negative.

Is this behavior expected? Can someone share as to why this could happen?

Is this a real violation? If so, how do we fix it?

Here's a sample from the VDD.vc.asc report file

Voltage source current violations:

      Range   Source    Source

      Index  Current    Name

      -----  --------   -------------

         8   -0.009268A   Vsrc116 (0) location 905440, -384620

         8   -0.009178A   Vsrc142 (1) location 905440, 415380

         6   -0.009511A   Vsrc166 (2) location 411960, 906300

         3   -0.00991A   Vsrc190 (3) location -303580, 906300

         7   -0.009438A   Vsrc95 (4) location 495380, -903640

         1   -0.01027A   Vsrc66 (5) location -348220, -903640
