Setup time violation on HBMC clock Domain

Hi

I am getting Setup Time violations on HBMC clock Domain (500MHz) due to Long Routing paths.

Type : Setup 'hbm_top_inst|iopll_t|iopll_t_outclk0'
Slack : -1.109
TNS : -863.275
Corner: Slow 900mV 100C Model

Type : Setup 'hbm_bottom_inst|iopll_b|iopll_b_outclk0'
Slack : -1.021
TNS : -1141.048
Corner: 1 Slow vid1 100C Model

Could you please suggest a fix for this issue?

Regards

Siva Kona

    Hi Richard Tan,

    Thanks for your reply!

    Setup Time Violation is in Intel IP (Quartus generated HBM IP)
