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:

	from numpy import exp, array, random, dot, sum, size, absolute



	class NeuralNetwork():

	def __init__(self, layer1, layer2):

	self.layer1 = layer1
	self.layer2 = layer2

	// C++ program to print DFS traversal from a given vertex in a given graph
	#include <iostream>
	#include <vector>

	using namespace std;

	// Graph class represents a directed graph using adjacency vector representation
	class Graph {
	int V; // No. of vertices
	void DFSUtil(int v, bool visited[]); // A function used by DFS
