Macrotest Command Dictionary

attempts and orderings, a message is issued for that pattern stating how many outputs were not observed for that pattern.

When using this option, macrotest is terminated (aborted) ONLY if the control (input) values cannot be created for some pattern. If this occurs, then macrotest must terminate because the expected outputs for subsequent patterns may no longer be correct. As long as the inputs can be created (data and clock pulses), macrotest will continue, issuing an informative message for each pattern which has incomplete observation of the known macro outputs. Only known outputs are observed for any pattern with this option, therefore, no message is issued if a Don’t Care (X) output can not be observed. The informative message states the number of known outputs which were not observed, and remains silent for each pattern where all known outputs are observed.

∙-MAX_Path_attempts d

An optional literal that establishes the positive integer d as the value for the number of observation attempts which is used by the -random_observe switch. The default value for d is 5 if this option is omitted, but the -random_observe option is issued.

∙-Parityparity_file_name

When the det_observe switch is used (default), a path is found from each macro output to some scan cell or PO which is observable. This path is used for all tests. If the -verbose option is used (default), then the scan cell or PO where an output is observed is reported once at the beginning of the pattern conversion process. Also, the parity along that path (even number of inversions or odd) is reported. If the -parity option is supplied, the report is written to the parity_file_name which follows that option instead of to the transcript or logfile where output normally goes. The -no_replace default does not overwrite an existing file, whereas the -replace option allows an existing parity file to be overwritten.

∙-Replace

An optional literal that specifies to replace information in the existing parity_file_name.
