Old — A literal that specifies for FastScan to determine the output value of a level sensitive source state element by using the data that existed prior to the current clock cycle. FastScan then passes this value to the state element’s sink state elements. This is the default behavior of FastScan upon invocation.
New — A literal that specifies for FastScan to determine the output value of a level sensitive source state element by using the data from the current clock cycle. FastScan then passes this value to the state element’s sink state elements. FastScan limits the scope of this capture handling effect to the circuitry between the source and sink points. FastScan will not proagate the newly captured effect past the sink point.
X — A literal that specifies for FastScan to determine the output value of a level sensitive source state element by using the data from the current clock cycle unless the previous values are different from the current values. If the values differ, FastScan passes an unknown (X) value to the state element’s sink state elements.
∙-Te Old New X
A switch and literal pair that specifies how you want FastScan to handle the data capturing of trailing edge sensitive state elements. The literal choices are as follows:
