bsalinux: > I'm trying to start on the multi sheet and hierarchical features of gEDA. ... There is a small howto at: http://www.easy-asic.de/downloads/HOWTO_hierarchical_designs.pdf There is a tool to make hier. sheets at: http://turkos.aspodata.se/git/openhw/pdftosym/pintosym.pl it will create a sym file and create/update a templete sch file for the subsheet. An example is available at: http://turkos.aspodata.se/git/openhw/pdftosym/examples.pintosym/hier.pins Use pod2text view its doc: $ pod2text pintosym.pl ... Do some special action: source <file_format> The file we are creating is a "source"-symbol to be used for hierarchical/mult.page schematics. This special will change the normal symbol creation process: . the attribute "source=<file_format>" will be included . the file named by <file_format> will be checked and created or updated so it contains, for each pin, one net symbol with a (invisible) "net=value:1", and a (visible) "refdes=value" attribute, where value is equal to resp. pins pinlabel attribute. The net symbol to be used is decided by the first "source-map" line which <perl_expression> evals to true. source-map=<net-sym-name> <alignment> <dx> <dy> <perl_expression> ...
