Hello sir, I got the following error during the RING stage of my design: $ ring xverchip xverchip @@@@@@@ @ @@@@ @ @@ @@ @@@ @@ @@ @@ @@ @ @@ @ @@ @@ @@@ @@@ @@ @@ @@ @@@@ @@@ @ @@ @@@@@ @@ @@ @@ @@ @@@@@ @@ @@ @@ @@ @@ @@ @ @@ @@ @@ @@ @@ @@ @@ @ @@ @@ @@ @@ @@ @@ @@ @@ @@ @@ @@ @@ @@ @@ @@ @@@@@ @@@ @@@@@@ @@@@ @@@@ @@@@ PAD ring router Alliance CAD System 4.5.0, ring 2.11 Copyright (c) 1991-2002, ASIM/LIP6/UPMC E-mail support: alliance-support@asim.lip6.fr o reading netlists, layout views of core and pads. o reading file of parameters, including the placements of pads. o making equipotential list. o making the first placement of pads. o filling data internal structures. o reading the connectors positions of the core. o computing the best placement of the pads. o reading the connectors positions of the pads. o routing deportation of connectors. No space hasn't been found for the connector <vss> of the instance <xver>. I got the error above after using the graal tool to move and relocate the connectors metioned below, thereby correcting these errors: Distance between connector <acont> and connector <dir> of the core isn't big enough. Distance between connector <aout 7> and connector <enable> of the core isn't big enough. Distance between connector <enable> and connector <bin 7> of the core isn't big enough. In one of my queries last year, I reported a similar error. You replied and said : " Looks like that this problem does not come from ring but from your connectors placement, so the scr phase. Maybe the design is to small, so there's not enough space for all the connectors. You should look at the connectors placement with scr (.scr file)." http://www-asim.lip6.fr/alliance/mailing-lists/alliance-support/2001/0335.html Using the graal tool, I searched for instance 'xver' in the generated (xvercore1.ap) file of my design (error mentioned above. ) However no 'xver' instance was reported found in the layout. I used the instruction "scr -p -r -l 2 -i 1000 xvercore1" to route my design. Also, about the design being too small, I was thinking the design should have been too large for no connector-space to be found. Pls how could I "look at the connectors placement with scr(.scr file)" -- considering that I have no scr file and I generated the layout using the instruction I mentioned above . Another thing sir, the (.scr) file in the amd2901 tutorial has an Icon like that of an exe file and there are system files with (.scr) files. What do I do about it. Is the .scr file a text document file. Pls I'll appreciate help. Thanks GIIE --------------------------------- Do You Yahoo!? Send FREE video emails in Yahoo! Mail.
