could anyone pls clarify my doubt....
for my design i doesn't have stream out map file,
then i tried using default one gen. by SOCE.
the gds was exported without any errors or warnings..
but i couldn't able to see all the layers while i import this gds into Virtuoso!
is there any problem while we use tool gen map file?
what is the difference?
could anybody suggest me how to construct streamout map file w.r.t to tech.?
Hi Did you get any ERROR , WARINGS while importing Soce GDS on to Virtuoso ?? Please check the below at your end .1. during StreamOut check the log file in which it clearly gives you the information of the Metal layers and see if there is any thing related to your missing layer to fix at SOCE strimout.To fix at Virtuoso Strim-In .2. check the Layer mapping Information between Soce and Virtuoso . and it should map correctly .In your tech. it will be clearly mentioned the layer map table . from which you can get the right mapping information.
Sorry guys... maybe it's unrelated topic. Anyone know how to view a GDS file without having to stream-in? And how about comparing (XOR) 2 GDS files to see any changes?thanks
Hi ,1. You can view GDS with out Stream-in by a tool called calibre in RVE mode . 2. After running a rule file using any tools like calibre .. etc (XOR) in which you will give GDS's one Gold and other reference . there will be a results database in Outputted . the out file can even be loaded on to Soce encounter to view . (by using loadVio. Rep. )
Hi Sury,I believe there are a couple of free GDSII viewers out there - you'll have to Google for them. Also, if you have Calibre, it has a good xor utility. Look up create_compare_rules in the Calibre docs.- Kari
Sandeep,The library vendor should have included a dfII tech file and/or a gds layer map file. You should start with one of these to create the FE gds map file.- Kari
