How to calculate 'Hold' time in the endpoint report?

yamakazu

Hi,

I want to know how to calculate 'Hold' time in the endpoint report to identify what is wrong. Could you give me the formula to calculate this? Is there any commands to list them up?

Path 1: VIOLATED Hold Check with Pin SW_SD_PAT_Gr_SW_SD_PAT1_M_SD_SEL32_FF_DTS_
KffF8_O1_reg_6/CK
Endpoint:   SW_SD_PAT_Gr_SW_SD_PAT1_M_SD_SEL32_FF_DTS_KffF8_O1_reg_6/D (v)
checked with  leading edge of 'CLK400M'
Beginpoint: SW_SB_RAM_M_U7076/A                                        (^)
triggered by  leading edge of 'CLK400M'
Path Groups: {reg2reg}
Analysis View: func_fhhb_sigrcmindp_erminus
Other End Arrival Time        208.536
+ Hold                        10787.407    <<=======  what is the formula to calculate this?
+ Phase Shift                   0.000
- CPPR Adjustment               9.873
- AOCV Adjustment               3.200

  • Hi,


    That value is extracted from timing library. I think that value is very large because it is out of range so the tool has extrapolated to that value. Hence, there is a problem with the timing library or the design.

    Regards.
