Symbol generation from table

[rdb]

I am making an FPGA symbol, and it has multiple hundreds of pins. I have a spreadsheet from the manufacturer on the pin schematic label vs pin number, so I’m wondering what the easiest way to generate this symbol (is this something that can be imported into kicad?). Right now I’m just manually creating each pin, double clicking, typing label and pin number…Hoping there is a smarter way.

kipart lets you create symbols from a spreadsheet. There are also some preprocessors for taking FPGA pin tables from manufacturers. I also created some FPGA libraries using it.

All of this uses KiCad V5 symbol tables, so you’ll have to convert it.

Another (and very simple) technique is to use Symbol Editor / Edit / Pin Table. It has an editable spreadsheet overview of all pins in a symbol and it supports copy & paste. I made a lot of use of it in the thread below (which turned into a sort of half-tutorial for a multi-part symbol).

Footprint for a 2-deck rotary switch

Hello All, I am trying to make a footprint for a Grayhill Series 71 PC mounted two-deck 12-position rotary switch. Attachment 1 shows the switch from the datasheet. Attachment 2 shows the schematic I am using. Attachment 3 shows the footprint I have developed so far. My question is: How do I tell Kicad that the two decks are on the same switch? Of course, any other advice about creating this footprint would be appreciated. Thanks in advance. ceulrich [Switch] [Schematic] [Footprint] …

Thanks all. I did try the Pin Table thing, but I couldn’t figure out how to spread the pins between different units. The pins would just appear in all units simultaneously for some reason, even though I had the “interchangeable” setting not selected.

Are you splitting it into power, prog, banks etc ? I have not tried this yet in Kicad, currently evaluating kicad to see if it can do all necessary. But I will have a go at it early if you have trouble

kipart looks useful, and also, user modifyable .
what FPGA?

OK I had a look at this.
The symbol pin table has UNIT field, so that should enable a unit aware import.
You might need to massage your import table to get unit allocation.

I was able to copy and paste in and out of excel just fine, modify unit allocations etc. Looks OK…

The PIN DELAY or PIN PACKAGE LENGTH field is missing from the table
I am getting that fixed . FPGA people need it here, not in 'package ’ LOL.

Also, for ease of import/export the location of the pins should not have the units mixed in with the numbers.

Length tuner is nice!, have delay questions,

Whoever wrote the trace length tuner , nice job . It’s nicer than the Altum tool. How is via delay set ? does it simply use the stackup (which is fine) ? of course depends on length traversed, IE L1 to L8 or L4 to L5. Where are component package delays/lengths set ? Altium has this set in the pin in the schematic symbol. We import the length or delay by copy and paste in usually using our own scripts. Pin information for a large chip gets imported from a CSV file so you dont have to add p…
