描述

The following CRITICAL WARNING might be seen in a design containing a connection between BUFMR and BUFR in the same clock region that cannot be routed.

Phase 7 Verifying routed nets
CRITICAL WARNING: [Route-54] Net: U0_EVA_IDI1TOP/U0_EVA_QDR2IPC/genblk1.U_QDR3MIG_IDI/u_qdr_phy_top/u_qdr_rld_mc_phy/qdr_rld_phy_4lanes_2.qdr_rld_phy_4lanes/n_cq_n is not completely routed.
CRITICAL WARNING: [Route-54] Net: U0_EVA_IDI1TOP/U0_EVA_QDR2IPC/genblk1.U_QDR3MIG_IDI/u_qdr_phy_top/u_qdr_rld_mc_phy/qdr_rld_phy_4lanes_2.qdr_rld_phy_4lanes/n_cq_p is not completely routed.
CRITICAL WARNING: [Route-7] Design has 2 unroutable pins, potentially caused by placement issues.
