Slack (hold path): -0.084ns (requirement - (clock path skew + uncertainty - data path))
Source: cgator_wrapper_i/rport/pcie_top_i/pcie_7x_i/pcie_block_i (CPU)
Destination: cgator_wrapper_i/rport/pcie_top_i/pcie_7x_i/pcie_bram_top/pcie_brams_tx/brams[0].ram/use_sdp.ramb36sdp/bram36_dp_bl.bram36_tdp_bl (RAM)

Slack (hold path): -0.075ns (requirement - (clock path skew + uncertainty - data path))
Source: cgator_wrapper_i/rport/pcie_top_i/pcie_7x_i/pcie_block_i (CPU)
Destination: cgator_wrapper_i/rport/pcie_top_i/pcie_7x_i/pcie_bram_top/pcie_brams_tx/brams[0].ram/use_sdp.ramb36sdp/sdp_bl.ramb36_dp_bl.ram36_bl (RAM)
