nport device S-parameter data file relative path
Hi,
In our design team, we're looking for a strategy to make all cell views self-contained. We are struggling to do so when nport devices are involved.
The nport file requires a full path, whereas what we need is a relative path to the current path of the cell in which we're using the nport.
I have browsed through the forums & cadence support pages, but could not find a solution.
1) There is a proposal from Andrew to add the file directory in ADE option "Simulation Files." :https://community.cadence.com/cadence_technology_forums/f/rf-design/27167/s-parameter-datafile-path-in-nport . This, however, is not suitable, because the cell is not self contained.
2) The new cadence version off DataSource "cellView" in nport options:
This however is not suitable for us due to two reasons:
i- Somehow we don't get this option in the nport cell (perhaps some custom modification from our PDK team)
ii- Even if we had this option, it requires to select the library, which again makes it unsuitable: We often copy design libraries for derivative products using "Hierarchical Copy" feature. And when the library is copied, the nport will still be pointing to the old library. Thus, it is still not self-contained.
In principle, it should not be difficult (technically) to point to a text file relative to the cell directory (f.ex we can make a folder under the same cell with name "sparFiles" & place all spar files under this folder), however it does not seem to be possible.
Could you perhaps recommend us a work-around to achieve our goal: making the cells which contain nport devices self-contained so that when we copy a cell, we do not have to update all the nport file destinations ?
Thanks in advance.
