Based on proposed PaaS platform, we developed the
application of test-pattern-conversion. Firstly it extracts all
information in the WGL file and stores it in a dynamically
created Waveform Database (WDB) with a propriety format.
And the database is manageable in a web-server environment,
the size of the test pattern, the use of CPU time and the
allocation of storage space are prescribed in advance. Overall,
the strategy of WDB is the key point of test-pattern-conversion
process. The second step of the pattern conversion is extracting
the WDB and regenerating the pattern according to the
specification of the target ATE. During such conversion, we
analyzed the restriction of different patterns and the format of
atp, and paid much attention on the edge information of the
waveform. The experiment have demonstrated that this app has
ideal functionality of converting the WGL file to atp file.
