Capnproto usage in VTR
Capnproto usage in Openfpga
======================
Capnproto is a data serialization framework designed for portabliity and speed.
In VPR, capnproto is used to provide binary formats for internal data
In Openfpga, capnproto is used to provide binary formats for internal data
structures that can be computed once, and used many times. Specific examples:
- rrgraph
- Router lookahead data
- Place matrix delay estimates
- preload unique blocks
What is capnproto?
==================
@ -29,56 +27,48 @@ These source and header files combined with the capnproto C++ library, enables
C++ code to read and write the messages matching a particular schema. The C++
library API can be found here: https://capnproto.org/cxx.html
Contents of libvtrcapnproto
Contents of libopenfpgacapnproto
===========================
libvtrcapnproto should contain two elements:
- Utilities for working capnproto messages in VTR
- Generate source and header files of all capnproto messages used in VTR
libopenfpgacapnproto should contain two elements:
- Utilities for working capnproto messages in Openfpga
- Generate source and header files of all capnproto messages used in Openfpga
I/O Utilities
-------------
Capnproto does not provide IO support, instead it works from arrays (or file
descriptors). To avoid re-writing this code, libvtrcapnproto provides two
descriptors). To avoid re-writing this code, libopenfpgacapnproto provides two
utilities that should be used whenever reading or writing capnproto message to
disk:
disk. These two files are copied :
- `serdes_utils.h` provides the writeMessageToFile function - Writes a
capnproto message to disk.
- `mmap_file.h` provides MmapFile object - Maps a capnproto message from the
disk as a flat array.
NdMatrix Utilities
------------------
A common datatype which appears in many data structures that VPR might want to
serialize is the generic type `vtr::NdMatrix`. `ndmatrix_serdes.h` provides
generic functions ToNdMatrix and FromNdMatrix, which can be used to generically
convert between the provideid capnproto message `Matrix` and `vtr::NdMatrix`.
Capnproto schemas
-----------------
libvtrcapnproto should contain all capnproto schema definitions used within
libopenfpgacapnproto should contain all capnproto schema definitions used within
VTR. To add a new schema:
1. Add the schema to git in `libs/libvtrcapnproto/`
1. Add the schema to git in `libs/libopenfpgacapnproto/`
2. Add the schema file name to `capnp_generate_cpp` invocation in
`libs/libvtrcapnproto/CMakeLists.txt`.
`libs/libopenfpgacapnproto/CMakeLists.txt`.
The schema will be available in the header file `schema filename>.h`. The
actual header file will appear in the CMake build directory
`libs/libvtrcapnproto` after `libvtrcapnproto` has been rebuilt.
`libs/libopenfpgacapnproto` after `libopenfpgacapnproto` has been rebuilt.
Writing capnproto binary files to text
======================================
The `capnp` tool (found in the CMake build directiory
`libs/EXTERNAL/capnproto/c++/src/capnp`) can be used to convert from a binary
`/vtr-verilog-to-routing/libs/EXTERNAL/capnproto/c++/src/capnp`) can be used to convert from a binary
capnp message to a textual form.
Example converting VprOverrideDelayModel from binary to text:
Example converting UniqueBlockCompactInfo from binary to text:
```
capnp convert binary:text place_delay_model.capnp VprOverrideDelayModel \
< place_delay.bin > place_delay.txt
capnp convert binary:text unique_blocks_uxsdcxx.capnp UniqueBlockCompactInfo \
< test.bin > test.txt
```
