bb-invoke-abc (DEPRECATED in v1.3)
SkillDev tools**[DEPRECATED in v1.3 — common path uses bb-invoke-yosys' embedded ABC]** 独立调用 ABC(Berkeley Logic Synthesis)做逻辑优化,仅 `mapping_effort=high` 等高级调优场景使用。触发场景:(1) bb-invoke-yosys `chain_to_abc=true` 时;(2) 显式 /bb-invoke-abc 调试。

在 99% 路径上
bb-invoke-yosys内嵌的 ABC 已足够。本 skill 仅保留为:
- high-effort 二次优化(fix L-02 / M-06)
- ABC script 单独调试场景
职责
读 Yosys 输出的 BLIF,跑自定义 ABC script 序列,输出优化后 BLIF。通常 bb-invoke-yosys 内嵌 ABC 已足够;本 skill 用于 high-effort 路径。

Input Args
| arg | type | required | 默认 | 说明 |
|---|---|---|---|---|
| blif_input | path | true | — | Yosys 写出的 BLIF |
| tech_lib | path | true | — | ASAP7 Liberty |
| script | string | false | "strash; iresyn; dc2; map -a" | ABC 命令序列 |
| design_name | string | true | — | — |
| stamp | string | false | <auto> | — |
Output Contract
| field | 值 |
|---|---|
artifact_path | designs/<name>/synth/abc_<stamp>.blif |
script_path | designs/<name>/synth/abc_<stamp>.script |
log_path | designs/<name>/synth/abc_<stamp>.log |
and_gates | int |
levels | int |
valid | bool |
error | string|null |
4-Phase 执行
Phase 1 — render_abc_script
scripts/render_abc.py 渲染:
read_blif <blif_input>
<script_commands>
map -a -B 0.33
write_blif designs/<name>/synth/abc_<stamp>.blif
print_stats
Phase 2 — run_abc
scripts/run_abc.py:
source ~/wrk/eda_opensources/eda_env.shtimeout 600 abc -f <script> > <log> 2>&1- log 追加
exit:<rc>
Phase 3 — parse_abc
scripts/parse_abc.py 解析 print_stats 行 nd = <int> ... lev = <int> → and_gates / levels,log 含 ERROR → valid=false。
写 abc_<stamp>.json。
Phase 4 — return
返回 JSON。bba-guru-synthesis 可将优化后 BLIF 反导入 Yosys read_blif 继续技术映射。
收敛 / 失败
| 状态 | 行动 |
|---|---|
| valid=true | 反导入 Yosys 或直接交付 |
| valid=false(log ERROR) | 退回默认 abc_options |
| Phase 2 timeout(600s) | error="ABC_TIMEOUT",简化 script |
注
独立调用属于高级优化场景。普通流程使用 bb-invoke-yosys 即可。
