<Zorix> ordered the ice breaker, it looks quite nice

<q3k> there's some VHDL/Verilog support plugins for IntelliJ
<q3k> but I've never used them

<Zorix> hmm
Bob_Dole has joined ##openfpga
<Zorix> what dev board would have something with >40 io lines?
Bob_Dole has quit [Ping timeout: 260 seconds]
<nats`> not sure a lot of ice device have those IO available
<Zorix> found some like LP1K
forrestv has joined ##openfpga
<Zorix> hmm the HX8K looks good but they only have a 40 pin dev board.. that would work for one project I'm working on, but others it would not
<Zorix> ah nm it just has one 40 pin populated header, it has 3 more, ok that does work
<nats`> those package are really easy you'll quickly make your own board
<Zorix> hmm, never did bga before
<Zorix> its cool though, pretty much got everything figured out except figuring out the constraint pin naming
<Zorix> ah, seems like it's the actual physical pin number
<TD-Linux> the hx1k is available in an ezpz tqfp100 package
<TD-Linux> or even tqfp144
<Zorix> yeah, actually end goal is to create replacements for custom vintage chips in DIP and PLCC by encapsulating a tiny fpga and all the level shifting and voltage conversion
<Zorix> I don't know if its actually achievable though with the kind of physical constraints
<TD-Linux> with the bga packages it is
<Zorix> was thinking it was possible yeah
<TD-Linux> I have made DIP40 packages with level translators for all the pins in tssop
<TD-Linux> (parts on both sides tho)
<Zorix> oh, do you have any pictures?
<Zorix> I actually want to cut actual legs and encapsulate everything
<TD-Linux> no but I have a kicad project https://github.com/tdaede/toshiba-64mbit-adapter
<Zorix> make it look real
<Zorix> cool will look at that, kicad is nice, I did my last pcb in kicad
<TD-Linux> a qfn part would also be an option
<Zorix> yosys synth_ice40 target applies to all ice40 models?
<awygle> yes
<Zorix> thanks!
<Zorix> will definitely go through those
<Zorix> I was actually looking at that one
etrig has quit [Remote host closed the connection]
<Zorix> so, for the HX8K, it's not clear based on the pinout diagram which numeric pin is used for the constraint file
<Zorix> it gives a ball number, which is a letter and number
<Zorix> I assume that doesn't work
<TD-Linux> it's just pin numbers
<Zorix> yes thats for icebreaker
<Zorix> I'm talking about for the HX8K which uses ball numbers
<Zorix> for example, IOL_1A is on ball number E4 for the caBGA package
<Zorix> I assume I can use ball number even though it's not numeric?
<awygle> eys
<Zorix> thanks!
<Zorix> thats all the questions I have tonight, you all have been extremely helpful and I greatly appreciate your tolerance to my questions

<zyp> this feels like a stupid question, but on ecp5, are there any benefits from using the dedicated pll inputs rather than the PCLK inputs, apart from leaving the PCLK input available for other use?
<daveshah> Marginally less jitter going into the PLL, probably
<daveshah> It would be a fairly specific application to actually care about that through
<zyp> figured that might be the case
<zyp> as far as I can see, the downside of the dedicated pll inputs is that they can only feed one specific PLL each
<zyp> and the ones in the top side banks can only feed the top side PLLs, which are not present in 25F
<zyp> I want to keep my design compatible with 25F, and I'm already out of IO in the left and right side banks :)
