A-Z80 Logic Design
|
2 |
|
|
==================
|
3 |
|
|
Each functional block contains a Quartus project file:
|
4 |
|
|
.//test_.qpf
|
5 |
|
|
|
6 |
|
|
Quartus projects are only used as containers for files within individual
|
7 |
|
|
modules; complete and working top-level solutions that use A-Z80 are in the
|
8 |
|
|
"host" folder.
|
9 |
|
|
|
10 |
|
|
Majority of sub-modules are designed in the Quartus schematic editor and then
|
11 |
|
|
exported to Verilog for simulation and top-level integration.

Simulation
|
14 |
|
|
==========
|
15 |
|
|
Before you can load and simulate any module through Modelsim, you need to set up
|
16 |
|
|
the environment by running 'modelsim_setup.py'. The script creates relative file
|
17 |
|
|
path mapping to source files in all module project folders.
|
18 |
|
|
|
19 |
|
|
Each functional block, including the top level, contains a Modelsim simulation
|
20 |
|
|
profile: .//simulation/modelsim/test_.mpf
|
21 |
|
|
|
22 |
|
|
After opening a Modelsim session, create a library and compile sources:
|
23 |
|
|
ModelSim> vlib work
|
24 |
|
|
Compile->Compile All
|
25 |
|
|
Run a simulation through one of the defined configurations.
|
26 |
|
|
|
27 |
|
|
If you get a message "Unable to compile", you likely forgot to run 'modelsim_setup.py'.
|
28 |
|
|
Exit ModelSim, revert changes to ".mpf" file, delete "work" folder and run
|
29 |
|
|
'modelsim_setup.py'.
|
30 |
|
|
|
31 |
|
|
Each project contains a set of predefined waveform scripts which you can
|
32 |
|
|
load before running a simulation:
|
33 |
|
|
.//simulation/modelsim/wave_.do
