ILOGIC / OLOGIC

  • IDDR DDR_CLK_EDGE=SAME_EDGE_PIPELINED now supported (fixes #65).
  • Placed BUFRs are configured and BUFR_DIVIDE is honoured (PR #151).
  • MMCM no longer held in reset forever (fixes #79). The RST path is now wired through so an external reset actually deasserts.
  • OSERDESE2 emits IS_CLKDIV_INVERTED and OSERDES.TRISTATE_WIDTH.W4 / IFF.INV_OCLK are configured.
  • IBUFGDS accepted as an alias of IBUFDS (fixes #74).
  • IDDR/ILOGIC fixes: all four IFF flops initialised for an IDDR; no more SRTYPE assert on the combinatorial pass-through; routethru/OSERDES dynamic inversion configured.
  • Diff-pair pin errors say which pin is wrong when a pair is constrained backwards (fixes #9).

Memory

  • SDP BRAM opposite-side port widths (PR #150). The unused port's width bit is no longer emitted, and 36-wide width markers no longer collide with the other port's width field.
  • RAM256X1S mux tree placed in its own slice half (was corrupting the SPO half); RAM128X1S scalar A0..A6 wired into the DRAM control set.
  • Registered BRAM outputs emit ZINV_REGCLKARDRCLK / ZINV_REGCLKB.
  • SRL cascades place like carry chains, with long chains routed via Q.

Placement & Routing

  • LUT6_2 → MUXF7/8/9 use-after-free fixed (PR #148).
  • Carry-chain fanout overhaul (PR #134): carry-O fabric fanout relocated, chain splits and sum duplication, spine links and row spread, carry-split livelock fixed.
  • Router2 wire reservation is now conflict-aware — fixes the 0.9.x counter-routing failures.
  • Final timing analysis runs after router2 (PR #139).
  • Heap legaliser robustness: placer1_refine failures propagate instead of hanging, budget-radius growth guard, eviction as last resort, deterministic fallback for sparse site types.
  • Slice egress validity and cross-position carry→FF pairings enforced (PR #146).

XDC / Timing

  • set_multicycle_path -setup supported in the XDC parser and timing engine.
  • Combinational loops warn instead of aborting the timing walk.
  • XDC diagnostics: warn on target selectors matching nothing (fixes #99), -quiet mode (PR #140), Vivado-style name[0] one-bit bus ports (fixes #46), IDELAYCTRL with no I/ODELAYs is a warning not an error (fixes #60).

Misc

  • FASM output records a run-identity header (PR #153).
  • PLLE2 LKTABLE/TABLE programmed from PLL-specific tables (PR #138); CLKFBOUT_MULT_F range-checked instead of crashing (fixes #78).
  • --report flag for timing + utilization JSON (mainline-style).
  • CI: per-PR demo-project regression gate; demo bitstreams uploaded as artifacts.

Notable external bumps: prjxray-db to d17fea2 (artix7 ilogic sameedge-pipelined segbits, PR #6) and further artix7/kintex7 HP-bank IOB segbits.
