    ModelSim Installation issues

Ubuntu 14.xx and above

Ignore this if you have not encountered any issue with the installation and running of ModelSim and Quartus on your system. You are very lucky. (Just Kidding! You have surely had this issue, only sorted.)
Hence assuming you have been following the procedure given in this guide. Most certainly, Quartus will install jsut fine, and so will ModelSim. The issue is in launching due to inappropriate linking etc.
Stage 1

This is the simplest error you would encounter. Navigate to the modelsim_ase folder and run:


## bbb_connect.sh
#!/bin/bash

#
# run this script on your linux host computer to connect to the bbb and forward your internet.
# be sure to replace "enp0s20u1" with the appropriate usb device for your bbb, which can be found
# by doing an "ifconfig" on your host computer.
#

sudo -- sh -c 'echo 1 > /proc/sys/net/ipv4/ip_forward'
sudo iptables -A POSTROUTING -t nat -j MASQUERADE
	#!/bin/bash

	#
	# run this script on your linux host computer to connect to the bbb and forward your internet.
	# be sure to replace "enp0s20u1" with the appropriate usb device for your bbb, which can be found
	# by doing an "ifconfig" on your host computer.
	#

	sudo -- sh -c 'echo 1 > /proc/sys/net/ipv4/ip_forward'
	sudo iptables -A POSTROUTING -t nat -j MASQUERADE
