yosys 在 ABC 通过时失败（在 counter.v 演示中）

Question

我希望有人能帮助我...

这是我第一次接触yosys。首先，我正在尝试运行与 Clifford 在他的演示文稿中解释的完全相同的演示。我在以下位置下载了演示：https://github.com/cliffordwolf/yosys/tree/master/manual/PRESENTATION_Intro

yosys 运行在 ABC 通行证上发出以下消息：

12. Executing ABC pass (technology mapping using ABC).

12.1. Extracting gate netlist of module `\counter' to `<abc-temp-dir>/input.blif'..
Extracted 6 gates and 12 wires to a netlist network with 4 inputs and 2 outputs.

[boris@E7440 yosys_synthesys]$

我看过上面报错的文件位置，里面没有output.blif:

[boris@E7440 yosys_synthesys]$ ll /tmp/yosys-abc-KDGya6/
total 12K
-rw-rw-r--. 1 boris boris 542 Jul  5 11:21 abc.script
-rw-rw-r--. 1 boris boris 526 Jul  5 11:21 input.blif
-rw-rw-r--. 1 boris boris 852 Jul  5 11:21 stdcells.genlib
[boris@E7440 yosys_synthesys]$

顺带一提，这里有一些 system/tools 可能与调试相关的信息：

Linux E7440.DELL 4.4.13-200.fc22.x86_64 #1 SMP Wed Jun 8 15:59:40 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Answer 1

问题已解决...

解= 更改了运行目录：

/home/boris/Documents/Self Learning/yosys_synthesys/mycells.lib

至：

/home/boris/Documents/SelfLearning/yosys_synthesys/mycells.lib

经验教训= ABC 工具不接受 path/file 名称中的 space 个字符。
