Abstract
The present invention provides a method and apparatus for efficiently loading values into scan and non-scan memory elements. First, the network used to distribute control signals to the memory elements is cleared. Second, the desired values are loaded into the scan memory elements. Third, the values from the scan memory elements are propagated to the non-scan memory elements.
Claims8
An apparatus for efficiently loading scan and non-scan memory elements in a logic circuit simulator, the apparatus comprising:
- means for clearing a signal distribution network coupled to the scan and non-scan memory elements;
- means for loading a previously determined set of values into each of the scan memory elements;
- and
- means for propagating the values from the scan memory elements to the non-scan memory elements.
A computer program product for efficiently loading scan and non-scan memory elements in a logic circuit simulator, the computer program product having a medium with a computer program embodied thereon, the computer program comprising:
- computer program code for clearing a signal distribution network coupled to the scan and non-scan memory elements;
- computer program code for loading a previously determined set of values into each of the scan memory elements;
- and
- computer program code for propagating the values from the scan memory elements to the non-scan memory elements.
