ysionneauI have an issue with nextpnr (or yosys?) while using IDDR ECP5 primitives: https://gist.github.com/fallen/9e5bf329b20e993a4b5210fb6dd1971108:45
ysionneauit says "ERROR: IDDRX2F 'IDDRX2F_3' D input must be connected only to a top level input"08:45
ysionneauHowever I've connected D to a top level input, but maybe it's because I'm using an array?08:46
ysionneauit seems to be this error https://github.com/YosysHQ/nextpnr/blob/master/ecp5/pack.cc#L212608:52
ysionneauah maybe it's the net->users.entries() > 1 ...08:53
ysionneaumaybe it's because I use the input both for D and some other logic meaning there will be some routing before the IDDR...08:54
ysionneaulet's try other way...08:54
ysionneauok works better if I re_use Q0 instead of D o/08:57
ysionneauproblem solved08:58
