Parallel Pattern
Schematic Symbol : PPattern
Simcode : 12003
This model generates a parallel pattern. The data bytes stored inside the memory of the model appears at the output, byte by byte, with a specified duration between each byte.
This instrument model is grouped under ‘Instruments’ category in the Schematic Browser.
How to simulate:
Invoke Mixed Mode simulator from EDWinXP Schematic Editor -> Preferences menu. Physical connections if any are made to the parallel pattern symbol and logic waveform marker is placed to view the waveform.
The simulation parameters are then assigned by selecting Tools menu-> Instruments-> Component Properties->Change Simulation Parameter and then clicking on the model.
The two modes of transmission available are continuous and interruptable. The style of transmission can be set as single or repeat. The parallel pattern varies according to the mode and style of transmission chosen. For interruptable mode, the Start Pattern button has to be clicked each time for individual byte transmission. The initial state and duration for a byte transmission can be varied.
On clicking Setup, an editor window pops up. This window can be resized as required. >In the window, select the Hex Editor tab and import the required *.BIN file containing data bytes in hexadecimal format and save.
Binary files that are already in the JOB folder can be edited and exported to .BIN format.
To simulate the model, select Simulation menu -> Analysis -> Transient analysis OR Oscillograph OR Logic Analyzer.
On clicking the Start Pattern button, the data bytes will be displayed in a parallel pattern that depends on the mode & style of transmission and other parameters specified.
