Yes, cross-probing of whole groups of symbols. > That is possible too, but still requires a project level overview of how > the netlister will transform refdes and netnames etc.. Sure. This means, the netlister has to be involved in the action. > Perhaps you could elaborate what Protel95 allows you to transfer. You select some symbols in the schematic and press a magic button. In the layout tool all the footprints that correspond to selected symbols will be selected. This is very useful during placement of analog circuits. Select a functional block in the schematics and the magic button allows to pick the corresponding components from the pile. With a layout that contains 500+ parts every means to divide and conquer the initial pile is welcome. Currently, I do this manually --- Look at the schematic, compile a list of refdeses, munge them in my head and write the list into the select-by- name dialog of pcb. > Please > bear in mind that until a lot of other work is done in gEDA, transfer > between apps which needs to know your workflow is not going to happen! The workflow of cross-probing might be implemented similar to the way parts are placed in the layout in the first place: 1) gschem collects the refdeses of a selection and writes them to an intermediate file. 2) gnetlist reads the file and appends/munges/converts them according like it is configured to to. The result is written to a second intermediate file. 3) pcb reads the list of munged refdeses and adds the corresponding components to the selection. A project manager GUI might reduce the hassle to the desired one-click- operation. This is very similar to an update of the layout after a change in schematic. None of the tools needs to know more about the actual workflow than it has to know now. ---<(kaimartin)>--- -- Kai-Martin Knaak http://lilalaser.de/blog _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
