2.3.2. Directory Structure
   The  Quartus® Prime Pro Edition software generates the design example files in the following folders: 
   
  - <user_defined_design_example_directory>/ed_sim
- <user_defined_design_example_directory>/ed_synth
- <user_defined_design_example_directory>/ed_hwtest
The following diagrams show the directories that contain the generated files for the design example.

  | Directory/File | Description | 
|---|---|
| ed_sim/tb_components | The directory that contains the testbench files. | 
| ed_sim/common | The directory that contains the .tcl scripts for all the simulators. | 
| ed_sim/cadence ed_sim/mentor ed_sim/xcelium ed_sim/synopsys/vcs ed_sim/synopsys/vcsmx | The directories that contain the simulation scripts. These directories also serve as a working area for the simulators. | 
| For simplex Tx/Rx mode: ed_sim/seriallite4_tx_0 ed_sim/seriallite4_rx_0 For duplex mode: ed_sim/seriallite4_dup | The directory that contains the design example simulation source files. | 
| ed_sim/seriallite4_tx_0.ip ed_sim/seriallite4_rx_0.ip ed_sim/seriallite4_dup.ip ed_sim/seriallite4_system_pll.ip | IP-XACT representation of the design. | 
| ed_synth/seriallite_iv_streaming_demo.qpf | Quartus® Prime Pro Edition project file. | 
| ed_synth/seriallite_iv_streaming_demo.qsf | Quartus® Prime Pro Edition settings file. | 
| ed_synth/seriallite_iv_streaming_demo.sdc | Synopsys Design Constraints (SDC) file. | 
| ed_synth/src | The directory that contains the design example synthesizable components. | 
| ed_synth/src/seriallite_iv_streaming_demo.v | Design example top-level HDL. | 
| ed_synth/demo_control | The directory for each synthesizable component including Platform Designer-generated IPs, such as Demo Management and Demo Control modules. | 
| ed_hwtest/sliv_ip_toolkit | The directory that contains the .tcl script and package files for the Serial Lite IV IP Toolkit. | 
| ed_hwtest/system_console | The directory that contains the system console scripts to provide useful commands for reading statistics and enables you to control various features in the design. |
