This page covers the creation and installation of a custom personality/bitfile (a modification of the vector adder sample project).
Building a Bitfile
Copy rev 2011_11_22 of the example project and set your environment variables if you have not done so already. You can make a small modification to the verilog code if you wish.
cd ~/pdk_sample/cae_vadd/phys make
The bitfile will take a long time to create (while the Reference Manual states 2 to 4 hours; mine took 18 hours to finish). Be patient.
Packaging the Bitfile
cd ~/pdk_sample/cae_vadd/phys make release
This will create a new directory (~/pdk_sample/cae_vadd.release/). The important file that is created is named cae_fpga.tgz.
Installing the Bitfile
Follow the instructions from section 9.4.7 to install the packaged bitfile.
- Rename ~/pdk_sample/cae_vadd.released/#DATE#/cae_fpga.tgz to ae_fpga.tgz
- Determine what your bitfile's signature should be
- Copy the ae_fpga.tgz file to /opt/convey/personalities/#signature#
Any ideas? We need higher privilledges add files to the /opt/convey/personalities/ folder.
Finally, flush the MP cache:
/opt/convey/sbin/mpcache –f
Choosing a Signature
The documentation (Section 10.1.2.1 of PDK Ref) also mentions doing the following:
cp –r /opt/convey/personalities/4.1.1.1.0 ~/#number=>65000#.1.1.1.0
Edit readme and PersDesc.dat.
Finally, you need to always set the CNY_PERSONALITY_PATH environment variable to
the directory just created, i.e.
export CNY_PERSONALITY_PATH=/home/my_dir/
or
setenv CNY_PERSONALITY_PATH /home/my_dir/
where /home/my_dir is your home directory or the directory #number=>65000#.1.1.1.0 was created in.
After implementing the AE software model, copy the AE software model executable into the #number=>65000#.1.1.1.0/ directory with the file name caeemulator. This allows the model to be automatically executed when the personality is dispatched by an application. Alternatively, the CNY_CAE_EMULATOR can be used to define the full pathname of the AE software model executable
