    @phoenixpavan: I'm using SOCE... @lostinxlation: I think they must be noted in library... i wanna know the way how to find this details in lef.... ;) @richtbiscuits: Ya, it's right. i've already seen that, It has R90. If R90 means we can rotate only 90degree or MX90, R180,270...

    Related to Clock latency interview question!!!

    Hi all, I know what is clock latency.. My question is " Assume that we are fixing the CTS with 10ns. Now we need to reduce the latency to 5ns." what should i do in design? Or what are the different way to reduce the latency? Plz reply...... I have such a lot of doubts in...
