Routing info in Cadence Encounter

Calistudent

Hello,

 After running Cadence Encounter, if I want to find out routing and layer information about particular nets, which report files should I use ? Which files will contain this info.

 Thanks in advance,

Nil.

  • Great suggestions here so far- thanks a lot to the customers helping out!

    A couple of additional options I'd offer up for your consideration:

    • Have a look at the reportWire command.  Here is some sample output: 
      ratio     wire_length   manhattan    vias  fanIn  fanOut net_name
                              length
      -------------------------------------------------------------------------
      1.08 Total  177.090     164.16 Total  4     1      1   dOut2[1]
         M1         7.650       V01   0
         M2       103.440       V12   2
         M3        66.000       V23   2
         M4         0.000       V34   0
         M5         0.000       V45   0
         M6         0.000       V56   0
    • You could use dbGet to query information about wire segments.  For example, if you wanted to know the layer of each wire segment for a given net:

      encounter 34> dbGet [dbGet -p top.nets.name tdsp_portO[14]].wires.layer.name
      M6 M6 M2 M3 M3 M4 M6 M5
    More information on getting started with dbGet can be found in this blog entry by Kari Summers.
    Hope this helps!
