Files are generated from a Viewlogic conversion utility to mentor format.

Get files using <http:> or <ftp:>.

Make the following further tweaks to the netsfile before starting layout:

All CK06-100 100n -> CK05-50 56n

  1. Notes
    1. TP1 should be placed in clear a board area in the middle of the card.
    2. VDEM is a power signal and requires large tracks.
    3. VRAM and GND are all power planes.
      GND should be on its own internal layer. VDD and VRAM should share an other internal layer
    4. Component heights are limited:
      ABOVE to 7.2 mm
      BELOW to 4.7 mm
    5. VDR is a power signal and requires large tracks.
  2. Feedback from Mentor

The final netslist files after completion of the layout should be saved here:

ftp://128.40.70.7/Public/Mentor/PROC as "QM_Mentor_Net" and "QM_Mentor_Comp"
