Introduction

This document describes how to connect user defined digital signals to eHS Gating Inputs that will be selectable in Schematic Editor via DI connections on singles switches, TSBs and other switching components.

Requirements

• eFPGASIM 2.18 and higher

• RT-XSG 3.7 and higher

Connecting user defined gating inputs to eHS Gen5

Since all inputs of eHS are now generic with eHS Gen5, to connect custom digital input signals, simply increment the Number of gating inputs parameters to add a new gating input port. Each gating input of eHS Gen5 expects 32 digital signals of 5bits if oversampled and 1bit if not.

Open

With the new port added, create and connect your digital signal generator to a Digital Input Mapping block. Again, make sure the format is 32 digital signals (eHS asserts the required type). Open the Digital Input Mapping block and select Other as the source of Channel 1. Name the source and set the number of signals to 32. Connect the signal generator the the input of the Digital Input Mapping block. Connect the output of the Digital Input Mapping block to gating input port previously added to eHS.

Open

With this completed in the XSG firmware model design, generate the bitstream and import the .ioconf firmware description file to Schematic Editor to see your digital inputs signals in the DI mapping of switching components.
