I think that the problem may lie in my testbench but i don't know where. Therefore select ‘full visibility’ in the tab Optimization Options. Optimization improves simulation speed but during debugging not all signals and variables are visible. In case a licenced version of ModelSim/QuestaSim is used optimizations it is on by default. C:\altera\13.0sp1\modelsimase\win32aloem Select OK. The directory should be located under the Altera directory, e.g.
for instance symbols = 12, addr_width = 4, maxhight = 13 worked, but symbols = 50, addr_width = 6, maxhight = 51 don't. In the ModelSim-Altera starter edition Enable optimization is disabled. For ModelSim-Altera, type the path or browse to the directory containing ModelSim-Altera. I change the amount of input by change the value of parameter TOTAL_SYMBOLS and parameter ADDR_WIDTH (size of address to account for total symbols = log2(TOTAL_SYMBOLS)) and maxhight (assume max hight of tree).

#Modelsim altera 13 32 bit#
(i'm using the 32 bit version of modelsim altera, some suggest that i may run out of memory, but i'm pretty sure i'm far from reaching that) but when i amp that number up, say 50 (which i have redeclare in the input file), i encounter an simulation error. Creating a Waveform Simulation for Altera FPGAs (Quartus version 13 and newer) (Sec 4. Under the EDA-Tool ModelSim-Altera type C:\altera\13.1\modelsimase\win32aloem to be the Location of Executable. Generating a test bench with the Altera-ModelSim simulation tool.
Go to the toolbar and select Tools Options General EDA Tool Settings 20. Once ModelSim has been installed open Quartus. Thing went smoothly for small number like 12 variable (12 numeric values of the amount of time that symbol appear aka frequencies). Ensure that ModelSim is going to be installed in the C:\altera\13.1 directory. The result should display all the encoding binary of input then write it to the appointed hex file. So i'm attempting a Huffman coding simulation from a list of symbol's character frequencies from hex file.
