    SCHEMATICONLY option in pex OUTPUT giving error in Caliber View

    manas

      Dear All,

      I used SCHEMATICONLY option in pex OUTPUT to avoid nox_ref warning.


      But then when I got calibre view ( with  Device location option as "Layout Location" just when PEX asks for giving option for Calibreview generation),

      in CIW window I got some errors like some nets are getting shorted in the Calibre View.

      I went and saw in the schematic of Calibre View that some components are overlapped on each other.

      The errors in CIW are:-

      Error: Net "I0_I0_I0_I1_I0_MNM40_b" shorted to net "I0_I0_I0_I1_I0_MNM43_b".

      \o Error: Net "I0_I0_I0_I1_I0_MNM40_s" shorted to net "I0_I0_I0_I1_I0_MNM43_s".

      Then I did PEX agian with Device location option as "Arrayed" just when PEX asks for giving option for Calibreview generation.

      This time the above error goes away. But in the Caliber View  I am getting some warnings like:-

      I wonder why I am getting these warnings ?

      Can anybody please tell how to avoid these type of warnings.


      Kind Regards,
