Currently it can process designs of size up to +4K gates. +.SS "GLOBAL ROUTING" +.PP +A design is considered as \fBbig\fR if it +contains nets which half perimeter is greater than 800 lambdas. +Global routing is used on big designs. +.PP +In nero, "global routing" means that +the longuests nets are completly routed in a first step with only +routing layers numbers 3 & 4. Then the smaller nets are routed with all +avalaibles layers. This implies that when global routing is +used, the number of routing layers is forced to at least 4. +In each step, the nets are routed from the shortest to the +longuest with the same routing algorithm. +.SH "INVOCATION" +.PP +nero mandatory arguments\ : +.TP 0.2i +\(bu +\fInetlist\fR\ : the name of +the design, whithout any extention. Please note that unless a +\fB-p\fR \fIplacement\fR option +is given, the file holding the placement is expected to have the +same name as the netlist file (short of the extention). +.TP 0.2i +\(bu +\fIlayout\fR\ : the name of +the resulting routed layout. Be careful of not giving the same +name as the netlist, in this case the initial placement will be +silently overwritten. +.PP +.PP +nero optionnals arguments\ : +.TP 0.2i +\(bu +\fB-h\fR, \fB--help\fR\ : +print help. +.TP 0.2i +\(bu +\fB-v\fR, \fB--verbose\fR\ : +be verbose. +.TP 0.2i +\(bu +\fB-V\fR, \fB--very-verbose\fR\ : +be unbearably verbose. +.TP 0.2i +\(bu +\fB-c\fR, \fB--core-dump\fR\ : +do not prevent the generation of core dumps in case of a crash. +Mostly used during the development stage. +.TP 0.2i +\(bu +\fB-2\fR, +\fB-3\fR, +\fB-4\fR, +\fB-5\fR, +\fB-6\fR\ : set the numbers of layers +used for routing.
