The COD is batter then the QFN package. It have 20mV lower than the QFN for both DVDD and DVDD_RAM. Does this means It is IR Drop problem? Can there any experiment I can do?
I have lower the chip DVDD LDO to 0.7mv. I provide the digital supply from the DVDD PIN so I could adjust the voltage from the external supply. What I said 1.0v and 0.99v is provide from the external supply. The abnormal I means CPU run out of control. Because I am digital engineer, I care about...
Hi
Our chip has passed the ss corner 0.99v -40c and ff corner 1.21v 125c at PT STA sign off. I expected the chip can work lower than 0.99v because it is tt coner and 25c degree. But when the chip comming back, It can only work at as low as 1.0v. The interesting thing is, temperature...
conformal abort
I think as stevepre said is right. I have a adder sharing. When I remove the adder the lec do not have any abort point. Can anybody tell me if I want keep the adder how can I do with the lec. Thanks!
lec multiplier
Now I use conformal to check the rtl and gate. The gate is synthesis by dc. But the conformal report some abort point. How to handle these abort points? How to make them equivelent? Can anybody help me!!
Thanks!
