Tips on using Quartus ModelSim Actions recommended before running simulation for the first time: 1. if not already done, install the Ubuntu package lib32ncurses5 2. to simulate VHDL code, in Quartus, under Assignments / Settings: in category EDA Tool Settings / Simulation: set Format(s) to VHDL (then button sequence Apply, OK) 3. in Quartus, under Tools / Options: in category EDA Tool Options: copy & paste ModelSim-Altera location to ModelSim location Action #1: thanks to Doron Behar and Qiu from http://stackoverflow.com/questions/31908525/modelsim-altera-error/31947317 Actions #2 and #3 are needed only once for Quartus 13.1, viz. their effects persist. On the contrary, with Quartus 16.0, action #3 is to be performed every time Quartus is launched (I'm not sure whether the same holds for action #2, I'll check it out asap). -- Author: Giuseppe Scollo, University of Catania, DMI Version: 1 Date: 14 October 2016
