I created a big multiplexer with Cadence Encounter and it has 4 metal layers. And to avoid some MTOP DRC error I filled the Top layer with metal dummies (rectangular dummies in Metal 4 connected to GND or floating).
But when I import tge GDSII in Cadence Virtuoso, all the layers and standard cells are present except the dummies I created in Cadence Encounter. I don't know why the dummies are not present because these dummies are just rectangular shapes in Metal 4.
Are the dummy fill layer types in your stream out mapping file from EDI? Likewise, make sure that layer is getting mapped in properly to Virtuoso.
In reply to wally1:
Yes, the layer is correctly mapped in virtuoso (I can see one or two of these dummies, but not the entire fill).
But I found an other way, I can fill the TOP metal directly in virtuoso with the Hit-Kit utilities, and it works very well (the dummies are floating, so I got a warning "Floating Met4" when I make the DRC but I don't think this is an error)
