3.7.2. Verifying the 10GbE Design in Hardware
After programming the targeted Altera device, follow these steps to verify your
design and collect the statistics:
1. Copy the csr_scripts directory to the design example directory.
2. Launch Qsys and access the System Console by clicking System Console on the
Tools menu.
3. Change the working directory to <project directory>/csr_scripts.
4. Type the following command to configure the design example:
source config.tcl
r
5. Start frame transmission on your remote partner to exercise the datapaths.
6. Type the following command to read and view the statistics:
source show_stats.tcl
r
1 The config.tcl and show_stats.tcl scripts support only one USB-Blaster
connection.
3.7.3. Debugging
You can use the system console to perform the following tasks for debugging
purposes:
■ Reconfigure the design example components and retrieve the registers during
runtime by following these steps:
a. Create a new Tcl script.
b. Add the following commands:
source common.tcl
# establishes the connection
open _jtag
# use rd32 to retrieve the register value
# base address = base address of the component
# offset = byte offset of the register
rd32 <base address> 0 <offset>
# use wr32 to configure the register
# base address = base address of the component
# offset = byte offset of the register
# value = value to be written to the register
wr32 <base address> 0 <offset> <value>
# closes the connection
close _jtag
Save and close the Tcl script and type the following command:
source <script>.tcl r
■ Retrieve and view the statistics counters by typing the following command:
source show_stats.tcl
r
