Title: Diva drcAntenna cumulative check
Post by giedrius on Nov 16^th, 2006, 1:55am

Hi all,
Does anyone know, how correctly write rules for cumulative check?
I've followed by divaref.pdf manual 339p. example:
......
ratio = if(diode 0 antenna / if(gate gate 1))
ratio = cumulative + byShape(ratio gate)
error(ratio > antenna_limit good msg ratio)
...................
, but have got following errors:
error: drcAntenna error expression does not allow both net and shape based values.
error: error clause ratio must be net based to match the expression.

It seems, that error clause want, that ratio expression will be net based.
But by example "ratio = cumulative + byShape(ratio gate)", it is shape based.
Where is a point?

Thanks, Giedrius
