在“abc”阶段失败了。 希望你能理解这个问题。
请您指导我解决这个问题。
答案 0 :(得分：1)
显然ABC无法解析你的自由文件：
ABC: Reading SCL library from file "/home/leela/synth/exp/scadv12atk_cmos10sf_hvt_ss_0p9v_125c.lib" has failed.
ABC: ** cmd error: aborting 'source <abc-temp-dir>/abc.script'
ABC: File "/home/leela/synth/exp/scadv12atk_cmos10sf_hvt_ss_0p9v_125c.lib". Line 64611. Failed to parse entry "".
ABC: Parsing failed. Parsing time = 0.10 sec
如果没有自由文件的副本，就不可能分辨出64611行中的ABC坏事。
