Peakrdl plugin for generated bluespec rtl from system RDL file.
This plugin takes an input file.rdl and generates three bluespec files
file_signal.bsvThis contains the module definition of each individual signal in the rdl file.file_reg.bsvThis groups the signals into their containing register module.file_csr.bsvThis creates a module with the registers, address decoding and S/W read write methods.
Installing the application
pip3 install peakrdl-bsv
Generating BSV files from test.rdl
peakrdl bsv test.rdl -o .
This can then be used in your design as follows
import file_csr::*;
...
ConfigCSR_file csr <- mkConfigCSR_file;
rule xyz;
csr.reg.signal.write(...)
endrule
The hardware side methods defined on a signal module are
method Bool pulse()returns true when a 1 is written to the signal. self clearing.method Bool swacc()returns true when a s/w read or write operation is performed.method Bool swmod()returns true when a write or a read with sideeffect operation is performed.method Bool anded()Returns an AND reduced value of the signal.method Bool ored();Returns an OR reduced value of the signal.method Bool xored()Returns an XOR reduced value of the signal.method Action clear()Set's the signal to 0.method Action _write(Bit#(n) data)writesdatato the register.method Bit#(n) _readReturns the value of the register.
To see an example
cd tests
make
This will generate the required files from the test.rdl file
