RgGen: Open source CSR generation tool

[Taichi Ishitani]

Hi All,

I'm developing an open source CSR generation tool named RgGen.
https://github.com/rggen/rggen
By using RgGen, you can generate UVM RAL models, RTL, C header files and wiki documents from readable register map specifications.

This is a sample register map specification describing a CSR block for an UART IP.
https://github.com/rggen/rggen-sample/blob/master/uart_csr.yml
RgGen can generate source files listed below from this specification.

• UVM RAL model
  https://github.com/rggen/rggen-sample/blob/master/uart_csr_ral_pkg.sv
• RTL
  https://github.com/rggen/rggen-sample/blob/master/uart_csr.sv
  https://github.com/rggen/rggen-sample/blob/master/uart_csr.v
  https://github.com/rggen/rggen-sample/blob/master/uart_csr.vhd
• C header file
  https://github.com/rggen/rggen-sample/blob/master/uart_csr.h
• Wiki document
  https://github.com/rggen/rggen-sample/blob/master/uart_csr.md

Hi Taichi,

Did you consider to use the IP-XACT register specification format as input for your generator? Any specific reason to use yaml and your own (?) specification format? Just curious.

I'm planning to add IP-XACT support.
But I have no experiences using IP-XACT so I'm looking into the specification now.

I think XML is not readable nor maintainable format for human so I chose the formats below.

• Ruby with description API
• Structured text (YAML, JSON, TOML)
• Spreadsheet (XLSX, ODS, CSV)
