Patent EP-0255118-A3 (EP)
IPC: G01R31/319
Filed: 1987-07-28
Abstract: This invention relates to a pattern generator 
(l00-l, ..., l00-N) permitting to output patterns with a 
high speed and having an operating function, which is 
suitable e.g. for generating test patterns for memory 
ICs. Although it was known heretofore to increase the 
operating speed by operating a plurality of pattern 
generators, for which patterns were generated from 
memories, in which patterns were previously stored, in 
parallel, it was not possible to operate pattern generators 
having an operating function in parallel. This invention 
is characterized in a method, by which the order of 
execution of operation processing instructions ( 
 - ) 
is assigned to each of the pattern generators and operation 
processing instructions are accumulated. According to 
this invention an effect can be obtained that patterns 
are generated with a high speed by means of a pattern 
generator having an operating function.
