You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computational vhdl computer program") OR ("using modulo python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational vhdl computer program\") OR (\"using modulo python python programming\"))".
• Removing quotes may allow a broader search: (( based computational vhdl computer program ) OR ( using modulo python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational vhdl computer program") OR ("using modulo python python programming"))*.
