In this case the net-list is flattened by the router according to the catalog file. The file format of the input files is set respectively by the environment variable \fBMBK_IN_LO\fP and \fBMBK_IN_PH\fP. +.br + +\fBoutput layout\fP +.br +The file containing the routed block will have the name \fIrouted_view\fP. The output format is defined by the environment variable \fBMBK_OUT_PH\fP. +.br + +.SH OPTIONS +.br + +\fBNumber of layers\fP +.br +\fB-l [0-9]+\fP +.br +This paramaters sets how many layers the router is allowed to use. The maximun is 5 (ie up to, and including, ALU6). The default is the minimum : 2, ie use only ALU2 and ALU3. + +.br + +\fBIterations\fP +.br +\fB-i [0-9]+\fP +.br +Tells the router to stop its main loop when it reaches N iterations. The default is to loop till core dump. +.br + +\fBVerbose mode\fP +.br +\fB-v\fP set the verbose mode on +\fB-vv\fP produces a lot of output +\fB-d\fP for debugging purpose +.br
