Title: DFF setup and hold time simulation methods Post by henry98 on Mar 20th, 2006, 10:40pm Hi, Guys, The DFF is one of the most important devices when desiging PLL. The one of the most performance is the DFF's setup and hold time. But till now we have't good solutions to how to simulate these parameter. So would you please give us some advice/information. Thanks a lot! henry |
