Altera HardCopy IV GX/E Pin Connection Guidelines

About this manual

This document provides preliminary pin connection guidelines for the HardCopy IV GX and HardCopy IV E programmable logic devices. It serves as a recommendation rather than a formal specification and must be verified against the official datasheet before use in any design.

The guide categorizes pins into Clock, PLL, and I/O sections, specifying connection rules such as tying unused pins to ground or using Quartus II software for internal biasing.
