His problem can be solved by adopting parameter configuring and TPCR model. The TPCR IP core is made up of the padded delay cell and re-synchronization cell. The padded delay cell specifies and restricts the interface timing of the IP core, making it possible for the SOC designers to estimate the margin of the interface timing at every design stage and making the IP core integrated in SOC seamlessly without the glued logic. The re-synchronization cell bridges different clock domains and asynchronous signals, ensuring that IP core carries out the transfer of the asynchronous signals.
