VHDL-Generics appeareing as "#define" in system.h

Question

Hello,

is there a way to propagate hardwareparameters of Avalon-Components to system.h

SOPC-Builder provides possibility to set values of generics, used in component's top level VHDL-files during instantiation of compoents.

How can the value, chosen within SOPC-Builder be propagated to e.g. system.h?

For my current projects i always have to make sure, that chosen generics match '#defines' for software projects.

THX

Did you ever get this to work? I would like to be able to do this. Regards, Rich

I realised I was trying to do something a bit different to the just getting a generic because my generic was set-able by the user.

The answer to my problem was to edit the hw.tcl file with the following

set_module_assignment embeddedsw.CMacro.TX_ARBITERLOCK [get_parameter_property allow_tx_arbiterlock HDL_PARAMETER]

set_module_assignment embeddedsw.CMacro.RX_ARBITERLOCK [get_parameter_property allow_rx_arbiterlock HDL_PARAMETER]

Hope this helps someone one day,

Rich

ok, all that did was say whether the items were HDL parameters. I needed to add a validation callback in the tcl file e.g.

set_module_property VALIDATION_CALLBACK validate

then at the bottom define the function

proc validate {} {

set_module_assignment embeddedsw.CMacro.TX_ARBITERLOCK [get_parameter_value allow_tx_arbiterlock]

set_module_assignment embeddedsw.CMacro.RX_ARBITERLOCK [get_parameter_value allow_rx_arbiterlock]

}

which does seem to work
