Hi, there
I am dealing with the back-annotated SDF timing simulation. The timing_vhdl file is generated by the Xilinx ISE tool and I applied it to the Modelsim simulator. But how can I obtain my original input/output signal? With older tools, I can identify, for instance, ..._D is the input of Data FF, ..._Q is the output of Data FF. But now I cannot trace these signals any more. It is dissappeard. How can I work around this problem? Which abbreviate is short for input or output of data flip-flop? I would appreciate any idea and suggestions. Thanks.
Chao.
