urg合并覆盖率报错

jjk1997

在使用urg合并覆盖率的时候，生成的.vbd文件里面只有xml文件，没有正常的结构，并且dve打不开，有没有佬知道怎么弄呢

urgmerge的log文件，好像有一些warning：Command: urg -full64 -dbname ./sim_results/cov_merge_report.vdb -log ./sim_results/urg_merge.log -format both -verbose -dir ./sim_results/regress/ahbl_mst_tight_transfer/iter_1/vdb.vdb -dir ./sim_results/regress/ahbl_mst_tight_transfer/iter_2/vdb.vdb -dir ./sim_results/regress/ahbl_mst_single_read32/iter_1/vdb.vdb -dir ./sim_results/regress/ahbl_mst_single_read32/iter_2/vdb.vdb -dir ./sim_results/regress/ahbl_mst_single_write32_apb_slv_nrdy/iter_1/vdb.vdb -dir ./sim_results/regress/ahbl_mst_single_write32_apb_slv_nrdy/iter_2/vdb.vdb -dir ./sim_results/regress/ahbl_mst_burst/iter_1/vdb.vdb -dir ./sim_results/regress/ahbl_mst_burst/iter_2/vdb.vdb -dir ./sim_results/regress/ahbl_mst_burst_apb_slv_slverr/iter_1/vdb.vdb -dir ./sim_results/regress/ahbl_mst_burst_apb_slv_slverr/iter_2/vdb.vdb
