* Fix icebox_vlog for up5kDavid Shah2020-06-291-1/+4
| | | | | | Since ce1d811, SHIFTREG_DIV_MODE is now 2 bits for the up5k Signed-off-by: David Shah <dave@ds0.me>
* icebox: Add support for the bit 1 of SHIFTREG_DIV_MODE on UP5kSylvain Munaut2020-06-031-1/+2
| | | | | | | | | | | | | This allows selection of the div-by-5 mode of the PLL. This bit can't be fuzzed because it's not supported by the lattice tools at all ... This only works for sure on the UP5k. I tested HX8k and it didn't support it, so I'm only adding this on the known working FPGA. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

| | | | | icecube uses SMCCLK.CLK to "legalize" output cells. Unclear what this is for, but it appears in almost all outputs.

| | | | 'self.lut_bits is None' was always false. The _lut_ keyword is used by asc2hlc, so when converting asc->hlc->asc the lut_bits were always all zeros.

| | | | | | | | | | | | | | | | | | | | | | | | As mentioned in ca6b2d9ebd521ecec58b9b5627c9380355adeab1, the 'routing' switches are not actually bidirectional. This makes the '<->' specifier very misleading. Instead use '~>' to differentiate it from the 'buffer' switches.
