To increase simulation speed, ModelSim® can apply a variety of optimizations to your design. These include, but are not limited to, mergingprocesses, pulling constants out of loops, CLOCK suppression, and signal collapsing. You control the level of optimization by specifying certain switches when you invoke the compiler.
This a vhdl programme for realise an electron watch by max-plus II. The function includes time showing and time setting. It may be extended to other functions like alarming CLOCK and so forth.
ST7529液晶驅動 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating CLOCK to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
This example program shows how to configure PCA Module 4 as a
watchdog timer. In this example, the watchdog is configured to
overflow after 0xFF00 CLOCK cycles.
