gEDA-user: ANN: vcd-0.0.0

2010-04-12 Thread Tom Hawkins
I uploaded a small library [1] for generating VCD files [2], which can be viewed with waveform tools like GTKWave [3]. Though VCD is commonly associated with Verilog simulation, at Eaton we use it to visualize vehicle data in realtime: data is pulled off the CAN bus, formated to VCD, then piped in

gEDA-user: GTKWave file formats

2010-04-11 Thread Tom Hawkins
Of the various formats supported by GTKWave (VCD, LXT, LXT2, VZT, FST, GHW), is there any consensus on which format has the best balance of file size and speed of parsing/generating? Are these formats formally defined anywhere? Currently our tool chains are based on VCD. But I'm starting a new r

Thanks for all the input. Here's the little hydraulic symbol library I started: http://tomahawkins.org/gschem-hydraulics.png http://github.com/tomahawkins/hydraulics A bit later I'll looking into path fills, and after that, netlisting this into something that can be simulated. Thanks for your h

2010-04-07 Thread Tom Hawkins
Hi, Obviously gschem is intended for electric circuits, but has anyone used it for hydraulic schematics? The hydraulics industry has defined a fairly rich schematic language [1][2] for describing hydraulic and pneumatic systems. I didn't find a gschem hydraulic symbol library, so I'm attempting
