Abstract: Based on two-Higgs-doublet model with soft CP-violation as an example, we analyze both the EDM and collider effects. In some region, different contributions to electron EDM may cancel with each other, thus an O(0.1) CP-phase is still allowed. We show the importance of neutron EDM test in such an scenario. For an O(0.1) CP-violation phase, first evidence will appear in future neutron EDM experiment to the accuracy O(10^{-27}) e.cm. Else the constriant on the CP-mixing angle will be an order stricter. We also analyze the CP-violation effects in ttH associated production process at LHC, which can provide a complementary cross-check.
