Protel has many rules, and often confilcts each other.
I meet a question about trace width rule.
for example: the trace witdth of net class D[0..16] is 1.3mm;
the whole board is 1.8mm. But actually D[0..16] is still 1.8mm.
I don't know why the added design rule is of no effect.
Besides I feel the FBGA components are very trouble Who can give me some
good advice about routing density pitch components just like FBGA.
I add one compent clearance rule, but it appears to no effect too.
