2019-02-22u4k: add SMCCLK cell locationSimon Schubert
icecube uses SMCCLK.CLK to "legalize" output cells. Unclear what this is for, but it appears in almost all outputs.

2018-07-19icebox_hlc2asc: fix _lut_ keyword parsingElms
'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.

This is done by sorting all the commands inside a block. Doing so makes it much easier to diff two files.

icebox: Fix driver detection for LUT cascade.
2018-06-12HLC: Use '~>' instead of '<->' for routing switches.Tim 'mithro' Ansell
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.
2018-06-12icebox_hlc2asc: Remove the bidirectional support.Tim 'mithro' Ansell
See ca6b2d9ebd521ecec58b9b5627c9380355adeab1.
