[Pkg-electronics-devel] Bug#1055171: fpga-icestorm: icebram incompatible with yosys 0.23

[Andras Pal]

Hi Daniel,

thank you - i removed the trixie packages, added your repo and upgraded 
the fpga-icestorm* packages accoringly. Tested on both this minimal 
example and on my larger projects - all passed and now working fine!

Yes, this thread is very interesting and discusses indeed the same issue. 
This distribution of BRAM cells for larger memory blocks is indeed 
implying an ambiguous solition and/or and interesting trade-offs (if we 
also consider things like power consumption vs. path lengths).

Thanks again, Andras
