关于dc综合的输入文件问题
1.
按照DC的说明,至少要有三样输入,这里并没有三项输入。
The minimum recommendedfiles are
至少包括:
o ${DCRM_CONSTRAINTS_INPUT_FILE} (Logical design constraints) 逻辑设计约束
o ${DCRM_DCT_DEF_INPUT_FILE} or ${DCRM_DCT_FLOORPLAN_INPUT_FILE}
(floorplan to use for topographical modesynthesis) topo模式所需要的floorplan
o ${DCRM_DFT_SIGNAL_SETUP_INPUT_FILE} (DFT signal definitions) DFT信号定义
逻辑设计约束在rm_dc_scripts下有,topo需要的floorplan没有,DFT信号定义没有。所以综合时会出现这几个warning:
Warning: File'pll_dig_dsm.def' was not found in search path. (CMD-030)
Warning: File'pll_dig_dsm.fp.objects' was not found in search path. (CMD-030)
Warning: File'pll_dig_dsm.fp' was not found in search path. (CMD-030)
Warning: File'pll_dig_dsm.physical_constraints.tcl' was not found in search path. (CMD-030)
那里文件不需要没有问题吗?需要最后还是综合出来版图了
ignore ,不是error 可以基本不看,
ignore ,不是error 可以基本不看,
dc综合时warning基本不管?
