[SOLVED] Need explanation about specific part of SDF file

[ebrahimi.khoy]

I am writing a simple SDF parser. In some rare cases I have one timing specifications instead of two. What is the reason?
Example:
Normal case: (IOPATH A1 ZN (0.061:0.062:0.062) (0.056:0.057:0.057))
Strange case: (IOPATH A2 ZN (0.064:0.065:0.065))
