11. Since the rise of reconfigurable programmable logic devices, sharing of logic designs has been a form of open-source hardware. 12. His patent ultimately improved the switching speed of saturated logic designs , such as the Schottky-TTL, at a low cost. 13. His earlier work was in the areas of systems modeling and simulation, logic design , computer architecture, and discrete mathematics. 14. In the late 1990s, the tool suite was known as " ldv ( logic design and verification ) ". 15. Sharp eventually made an agreement with Rockwell, which manufactured the QT-8D's LSI ICs for Sharp based on Sharp's logic designs . 16. In 1951 she accepted a job with the Electronic Computer Corporation and began there as head of the Logic Design Department. 17. He developed the chip and logic design together with the layout of all the chips of the 4004 family ( MCS-4 ). 18. While AltiVec refers to an instruction set, the implementations in CPUs produced by IBM and Motorola are separate in terms of logic design . 19. In the long term the lab plans to create its own core technologies, especially in chip design, logic design and real-time operating systems. 20. AHDL is used for digital logic design entry for Altera's complex programmable logic devices ( CPLDs ) and field-programmable gate arrays ( FPGAs ).
