用MODELSIM做后仿
编译后 ,加载SDC的时候报错
warning:# Loading pixel.sdf # ** Warning: (vsim-SDF-3438) pixel.sdf(307): Annotating cell drivers of INTERCONNECT source port. # ** Warning: (vsim-SDF-3438) pixel.sdf(308): Annotating cell drivers of INTERCONNECT source port. # ** Warning: (vsim-SDF-3438) pixel.sdf(309): Annotating cell drivers of INTERCONNECT source port. # ** Warning: (vsim-SDF-3438) pixel.sdf(310): Annotating cell drivers of INTERCONNECT source port. # ** Warning: (vsim-SDF-3438) pixel.sdf(311): Annotating cell drivers of INTERCONNECT source port.
SDF中 是 这几行:这5个是我的 输出端口
(INTERCONNECT START_CLKI_REG/Q
START_CLKI (0.0005:0.0005:0.0005) (0.0005:0.0005:0.0005))
(INTERCONNECT START_RESET_REG/Q
START_RESET (0.0007:0.0007:0.0007) (0.0007:0.0007:0.0007))
(INTERCONNECT CLK_1M_REG/Q

(INTERCONNECT RST_REG/Q
RST (0.0008:0.0008:0.0008) (0.0008:0.0008:0.0008))
ERRO是:# ** Error: (vsim-SDF-3262) pixel.sdf(332): Failed to find matching specify timing constraint. # ** Error: (vsim-SDF-3262) pixel.sdf(352): Failed to find matching specify timing constraint. # ** Error: (vsim-SDF-3262) pixel.sdf(372): Failed to find matching specify timing constraint. # ** Error: (vsim-SDF-3262) pixel.sdf(392): Failed to find matching specify timing constraint. #。。。。。。。。。。还有很多,每隔20行有个 # ** Error: (vsim-SDF-3262) pixel.sdf(848): Failed to find matching specify timing constraint. # ** Error: (vsim-SDF-3445) Failed to parse SDF file "pixel.sdf". #

我找了下 SDF中是每个CELL的RECOVERR那一行 :
(TIMINGCHECK
(SETUP (posedge D) (posedge CK) (0.0:0.0:0.0))
(SETUP (negedge D) (posedge CK) (0.0:0.0:0.0))
(HOLD (posedge D) (posedge CK) (0.0:0.0:0.0))
(HOLD (negedge D) (posedge CK) (0.0:0.0:0.0))
(HOLD (posedge RN) (posedge CK) (0.0:0.0:0.0))
(RECOVERY (posedge RN) (posedge CK) (0.0:0.0:0.0))
)
求教:这是什么问题啊?着急啊 |
