2 Introduction to OFS Evaluation Script¶
By following the setup steps and using the OFS evaluation script you can quickly evaluate many features that the OFS framework provides and also leverage this script for your own development.
2.1 Pre-Requisites¶
This script uses the following set of software tools which should be installed using the directory structure below. Tool versions can vary.
- Intel Quartus® Prime Pro Software
- Synopsys® VCS Simulator
- Siemens® Questa® Simulator
Figure 2-1 Folder Hierarchy for Software Tools
-
You must create a directory named "ofs-X.X.X" where the X represents the current release number, for example ofs-2023.1-1.
-
You must clone the required OFS repositories as per Figure 2-2. Please refer to the BKC table for locations. Please go [OFS Getting Started User Guide] for the instructions for the BKC installation.
-
Once the repositories are cloned, copy the evaluation script (ofs_f2000x_eval.sh) which is located at [eval_scripts] beneath the $IOFS_BUILD_ROOT directory location as shown in the example below:
Figure 2-2 Directory Structure for OFS Project
## ofs-2023.1-1
## -> examples-afu
## -> linux-dfl
## -> ofs-f2000x-pl
## -> opae-sdk
## -> opae-sim
## -> ofs_f2000x_eval.sh
- Open the README file named (README_ofs_f2000x_eval.txt) which is located at [eval_scripts] which informs the user which sections to modify in the script prior to building the FIM and running hardware, software and simulation tests.
2.2 f2000x Evaluation Script modification¶
To adapt this script to the user environment please follow the instructions below which explains which line numbers to change in the ofs_f2000x_eval.sh script
User Directory Creation¶
The user must create the top-level source directory and then clone the OFS repositories
mkdir ofs-2023.1-1
In the example above we have used ofs-2023.1-1 as the directory name
Set-Up Proxy Server (lines 65-67)¶
Please enter the location of your proxy server to allow access to external internet to build software packages.
Note: Failing to add proxy server will prevent cloning of repositories and the user will be unable to build the OFS framework.
export http_proxy=<user_proxy>
export https_proxy=<user_proxy>
export no_proxy=<user_proxy>
License Files (lines 70-72)¶
Please enter the the license file locations for the following tool variables
export LM_LICENSE_FILE=<user_license>
export DW_LICENSE_FILE=<user_license>
export SNPSLMD_LICENSE_FILE=<user_license>
Tools Location (line 85, 86, 87, 88)¶
Set Location of Quartus, Synopsys and Questasim
export QUARTUS_TOOLS_LOCATION=/home
export SYNOPSYS_TOOLS_LOCATION=/home
export QUESTASIM_TOOLS_LOCATION=/home
Quartus Tools Version (line 93)¶
Set version of Quartus
export QUARTUS_VERSION=23.1
In the example above "23.1" is used as the Quartus tools version
OPAE Tools (line 106)¶
change OPAE SDK VERSION
export OPAE_SDK_VERSION=2.5.0-3
In the example above "2.5.0-3" is used as the OPAE SDK tools version
PCIe (Bus Number) (lines 230 and 237)¶
The Bus number must be entered by the user after installing the hardware in the chosen server, in the example below "b1" is the Bus Number for a single card as defined in the evaluation script.
export ADP_CARD0_BUS_NUMBER=b1
The evaluation script uses the bus number as an identifier to interrogate the card. The command below will identify the accelerater card plugged into a server.
lspci | grep acc
b1:00.0 Processing accelerators: Intel Corporation Device bcce (rev 01)
The result identifies the card as being assigned "b1" as the bus number so the entry in the script changes to
export ADP_CARD0_BUS_NUMBER=b1
The user can also run the following command on the ofs_f2000x_eval.sh script to automatically change the bus number to b1 in the ofs_f2000x_eval.sh script.
grep -rli 'b1' * | xargs -i@ sed -i 'b1' @
if the bus number is 85 for example
85:00.0 Processing accelerators: Intel Corporation Device bcce (rev 01)
the command to change to 85 in the evaluation script would be
grep -rli 'b1' * | xargs -i@ sed -i '85' @
The ofs_f2000x_eval.sh script has now been modified to the server set-up and the user can proceed to build, compile and simulate the OFS stack

3.1.11 ADP BUILD ALL PROJECT MENU¶
Builds the complete OFS flow, good for regression testing and overnight builds
For this menu a user can run a sequence of tests (compilation, build and simulation) and executes them sequentially. After the script is successfully executed, a set of binary files is produced which a you can use to evaluate your hardware. Log files are also produced which checks whether the tests passed.
A user can run a sequence of tests and execute them sequentially. In the example below when the user selects option 46 from the main menu the script will execute 24 tests ie (main menu options 2, 9, 12, 13, 14, 15, 16, 17, 18, 32, 34, 35, 37, 39, 40, 41, 42, 43 and 44. These 19 menu options are chosen to build the complete OFS flow covering build, compile and simulation.
| Menu Option | Result |
|---|---|
| 46 - Build and Simulate Complete f2000x Project | Generating Log File with date and timestamp Log file written to /home/guest/ofs-2.3.1/log_files/f2000x_log_2022_11_10-093649/ofs_f2000x_eval.log |
Definition of Multi-Test Set-up¶
Menu Option 46 above in the evaluation script can be refined to tailor it to the users need and is principally defined by the variable below
MULTI_TEST[A,B]=C
where
A= Total Number of menu options in script
B= Can be changed to a number to select the test order
C= Menu Option in Script
Example 1
MULTI_TEST[46,0]=2
A= 46 is the total number of options in the script B= 0 indicates that this is the first test to be run in the script C= Menu option in Script ie 2- List of Documentation for ADP f2000x Project
Example 2
MULTI_TEST[46,0]=2
MULTI_TEST[46,1]=9
In the example above two tests are run in order ie 0, and 1 and the following menu options are executed ie 2- List of Documentation for ADP f2000x Project and 9 - Check ADP software versions for ADP f2000x Project
The user can also modify the build time by de-selecting options they do not wish to use, see below for a couple of use-case scenarios.
Default User Case¶
A user can run a sequence of tests and execute them sequentially. In the example below when the user selects option 46 from the main menu the script will execute 24 tests ie (main menu options 2, 9, 12, 13, 14, 15, 16, 17, 18, 32, 34, 35, 37, 39, 40, 41, 42, 43 and 44. All other tests with an "X" indicates do not run that test
User Case for ADP FIM/PR BUILD MENU¶
In the example below when the user selects option 46 from the main menu the script will only run options from the ADP FIM/PR BUILD MENU (7 options, main menu options 12, 13, 14, 15, 16, 17 and 18). All other tests with an "X" indicates do not run that test.
