Changing the file names of an SLX file can cause LUT errors during jasper compiles. These errors are fatal and will drop the compile to command line in Matlab. The CASPER toolflow official documentation should mention this problem, if -- for no other reason -- CASPER doesn't have a mechanism to check whether the current SLX filename has been changed
These LUT errors occur in the later stages of implementation, during the "Logical Optimization" stages. The blocks in the design which invoke the missing logic LUT error are random, and seem to be related to the order in which optimizer selects blocks for optimizing. For example, if the offending block is removed, the LUT error will migrate to some other -- often unrelated -- block in a different portion of the overall design. If that new offending block is removed, the LUT error migrates to yet another block, and so on ad infinitum. We might ask why this occurs. A name-changed SLX survives completely through the synthesis stage of jasper compile, making the error unusually pernicious. -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
