Support for Arty A7 100t

[vj-kumar]

Can we have support for synthesising necessary files for the 100t variant of digilent arty kit?

I'm not experienced enough in vivado tcl, seem like it would mainly be about https://github.com/SpinalHDL/SaxonSoc/blob/dev/hardware/synthesis/arty_a7/vivado_params.tcl#L2

@sebastien-riou Do you know a clean way of handeling such cases ?

[sebastien-riou]

should not be a big deal indeed. there is also https://github.com/SpinalHDL/SaxonSoc/blob/a89053c637cdbcb2c4ce93acae9dd32e429d8d21/hardware/synthesis/arty_a7/vivado_script.tcl#L16 to change. at some point we should have an argument to the make file I guess

I am also not very experienced in that. Below is the diff I used to test on a 100T variant. If someone is willing to send a patch based on these parts please feel free to send it. I was planning to have a look into it, but currently occupied and it might take some time.

i'm curious, was changing those scripts enough?

[vj-kumar]

As far as I remember, it was enough at that time.
