*** the config writes madness
|
||||
- step9 (sume simulation, the longest step) in the process calls
|
||||
"config_writes.py"
|
||||
- config_writes.py fails with a syntax error, as it is incomplete
|
||||
python code
|
||||
- config_writes.py and config_writes.sh are generated by
|
||||
gen_config_writes.py
|
||||
- gen_config_writes.py reads config_writes.txt
|
||||
- config_writes.txt is created in step 5 (sdnet simulation)
|
||||
- step 5 consists of running xsc, xelab and xsim
|
||||
- xsim (re-)generates config_writes.txt according to a watch ls -l
|
||||
on the file: ${XILINX_VIVADO}/bin/xsim --runall
|
||||
SimpleSumeSwitch_tb#work.glbl
|
||||
- it seems (by grep -r) that ./Testbench/SimpleSumeSwitch_tb.sv is
|
||||
responsible for writing config_writes.txt
|
||||
- It seems that the "task" "SV_write_control" inside that file is
|
||||
responsible for writing the content, which in turn uses
|
||||
axi4_lite_master_write_request_control
|
||||
|
||||
|
||||
**** More notes for the config writes madness
|
||||
xsc and xelab are described in
|
||||
https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwiGqfiAmcjjAhXEC-wKHW3_C78QFjABegQIBBAC&url=https%3A%2F%2Fwww.xilinx.com%2Fsupport%2Fdocumentation%2Fsw_manuals%2Fxilinx2014_4%2Fug900-vivado-logic-simulation.pdf&usg=AOvVaw1jgWuqcjeph5qOplb4eJMq
|
||||
|
||||
The xsc compiler helps create a shared library (.a on Windows or .so on Linux) from one
|
||||
or more C files. You use xelab to bind the shared library generated by xsc into the rest of
|
||||
your design. You can create a shared library using a one- or two-step process:
|
||||
|
||||
- the only file that matches the string "config_writes" in the
|
||||
nf_sume_sdnet_ip/SimpleSumeSwitch subdirectory is
|
||||
./Testbench/SimpleSumeSwitch_tb.sv
|
||||
|
||||
- code inside SimpleSumeSwitch_tb.sv:
|
||||
|
||||
#+BEGIN_CENTER
|
||||
task SV_write_control(
|
||||
input integer addr,
|
||||
input integer data
|
||||
);
|
||||
int file;
|
||||
file = $fopen("config_writes.txt", "a");
|
||||
$display("SV_write_control()- start");
|
||||
$fwrite(file, "<addr, data>: (%h, %h)\n", addr, data);
|
||||
axi4_lite_master_write_request_control(addr,data);
|
||||
$display("SV_write_control()- done");
|
||||
$fclose(file);
