How to use the relative-vars option in the ip-make-ipx

The help message of ip-make-ipx says:

--relative-vars=<value>

Optional. Comma-separated list of shell variables, to which relative references are preferred

 

What is the purpose of this option and how can it be used?

I have found that whatever I put into this option simply gets ignored.

<--relative-vars=> Description: Causes the output file to include references relative to the specified variable or variables wherever possible. You can specify multiple variables as a comma-separated list.

Specifying --relative-vars allows the usage of ENV variables to anchor the files that are found during the traversal.

e.g.

env var:
MY_DEST_ROOT=/data/user/ip/bar

ip-make-ipx --source-directory=/data/user/ip/bar/jon --output=/tmp/out.ipx --thorough-descent --relative-vars=MY_DEST_ROOT

You will get something similar like this:

<component
name="ip"
file=${MY_DEST_ROOT}/jon/ip_hw.tcl
...>
</component>

Do take note: It is Optional to use it and if you do use --relative-vars, IP_ROOTDIR and QUARTUS_ROOTDIR is not supplied anymore, so you will not see those applied to the .iipx files unless you specify them as well.

I created an environment variable and then put its name into the relative-vars. However, when the ipx file is generated, it does not contain the variable  name as if it has been basically ignored. I do not understand why this is so.

Hmmm...not sure why it does not show up in the file. I have filed to the engineering team to check on this. While the engineering may takes some time to fix this, you may use the absolute path name in your .ipx file. It should work as usual.

Hi @gyuunyuu 

 

I was able to make this work on my Windows machine. One thing I noticed was that you need to reboot your command prompt after you set your env var to take effect.

I used "echo %MY_DEST_ROOT%" to make sure the is active within that shell.
