    Clarification in SVRF script !!!

    chin

      Hi All

             While scripting in the SVRF I ran in to the problem. Since i am new I could not solve. Please suggest your comment.

       

      In the following codes I need to run the "rule 1" in Database and with the results of "rule 1" I need to run "rule 2"

      //Rule 1

      'm1_with_2_m1con'{
          @ This Li1 shape has 2 mcon ends
          mcon_END = size mcon by 0.095 inside of Li1 step 0.01
          Li1_MIDDLE = Li1 not mcon_END
          Li1_MIDDLE interact mcon_END > 1
      }

      //Rule 2

      Li1_length = LENGTH Li1 > 10

       

      "r_Li1_critial_net" {
          @ Li1 with 0.17 spacing running for more than 10um
          COPY Li1_length
          }

       

      As of now "Rule 2" is running in the complete database. what modification needs' to be made to acheive my need ?

       

      Thanks for your suggetions

      Chin

          Hi Chin,

           

          Combining those two checks should be very easy. Here is one way to consider:

           

          //Rule 1 and 2

          'long_m1_with_2_m1con'{
              @ This Li1 shape has 2 mcon ends
              mcon_END = size mcon by 0.095 inside of Li1 step 0.01
              Li1_MIDDLE = Li1 not mcon_END
              Li1_MIDDLE_2 = Li1_MIDDLE interact mcon_END > 1
              Li1_length = LENGTH Li1_MIDDLE_2 > 10

              FLATTEN Li1_length   // to see all results, not just representatives of repeated cells

          }

          I haven't tested this, but it looks like it should do what you want. Maybe you can test it and let everyone know how it goes for you?
