Issues

• synthesize emits an unwritable netlist when a latch survives on a library with no latch cell: place-and-route refuses with a raw syntax error

• klt power: provenance field for the current limit (current_limit_source) has no counterpart for sheet/via resistance

• klt extract: dead_metal_summary.area_um2 serializes as int 0 on the zero case, docs example shows 0.0

• signoff item 3 grades on status alone; disclosed coverage gaps are never compared against the claim

• array-check: --format json record carries no provenance block and an unanchored 'file' field, so the verdict cannot be committed as evidence

• klt signoff: multi-citation item-6 grade drops per-citation yield_campaign disclosures

• functional-verification: no PDK-aware way to name std-cell simulation models; sources must hard-code machine-relative paths

  2AMLogic/klayout-tools#5785 · Filter by author loom-fleet-dispatch opened on Nov 15, 2026

• functional-verification: reports echo options.sdf.file as an absolute producer path; committed evidence cannot stay checkout-free

• klt sta: the worst-path report gives endpoints and total slack but no per-stage delay breakdown, so a failing path cannot be split for retiming from a committed record

• functional-verification: no way to prepend a PDK's behavioural cell models to a gate-level re-sim, so every caller hardcodes host-specific model paths and an unstated define policy

• klt synthesize stalls to the 300 s timeout when TMPDIR is long: yosys-abc's wrapped source-echo breaks yosys's ABC reuse protocol

• klt: lint a device multiplier whose vendor 'mult' and acting 'm=' disagree (sky130 declares mult without forwarding it)

• klt sim --attach: help documents a batch-shards.json path but the runtime refuses any sharded attach

• klt sim batch: without --format json a fully-passing run exits 0 but writes no report file anywhere (results only on stdout)

• klt sim --resume on a partial sharded batch run re-submits every shard instead of reusing the collected corners

• Friction: klt sim has no way to pin or report the RNG seed governing trnoise/trrandom sources, so a transient-noise campaign's seeds are neither recordable nor reproducible
