Converters - Introduction¶

SimApp makes a distinction between binary and digital converters. This is not common practice but it is important to describe two types of digital transmission used in SimApp.

A digital input or output in SimApp consists of a single node that can transmit all bits at one time. The digital numerical value is transmitted as a positive analog integer signal, e.g. binary 0 corresponds to 0, 1101 (13 decimal) corresponds to 13. It does not make sense to mix digital and analog signals, therefore the digital signal lines differ in color from the standard signal lines. The advantage of this analog coding of digital values lies in the small space requirement on the drawing for the element and transmission (one line only).

The binary input and output in SimApp corresponds more to the usual concepts. For each individual bit, an individual signal line is used. The disadvantage of this solution is the huge space requirement for large numbers (big elements and multiple lines).
