MACRO_PLACEMENT_CFGm
Matt Venn
06/18/2021, 8:14 AMhow are you implementing your design then? the normal thing is to harden your design as a macro and then incorporate it into user_project_wrapper. user_project_wrapper is setup so it does no synthesis, so you can't have any logic or design in there.

06/18/2021, 5:07 PM@Matt Venn Yes, Thank you

I hardened my design successfully but now I'm a bit confused, how to instansiate the macro after that.
What I understood is that I've to copy the verilog codes under verilog/rtl directory then instansiate the top module inside the user_project_wrapper, by changing the user_proj_example to the top module name
m
Matt Venn
06/18/2021, 5:08 PMyou need to instantiate it inside ./verilog/rtl/user_project_wrapper.v and also reference it in ./openlane/user_project_wrapper/config.tcl and macro.cfg
👍 1
yeah
swap out the mprj example for your own
m
Mariam Zanaty
06/18/2021, 5:10 PMAnd to delete the interface ports with the picorv?
m
Matt Venn
06/18/2021, 5:10 PMdepends if you want to use them or not
you can't change the interface port of user_project_wrapper, but you can do what you want with any modules instantiated inside
m
Mariam Zanaty
06/18/2021, 5:11 PMYes, I got it
Thank you

Same error:(

Matt Venn
06/18/2021, 6:54 PMPost your repo
m
Mariam Zanaty
06/18/2021, 8:44 PMSorry for being this late, but if you could help please.
m
Matt Venn
06/18/2021, 9:01 PMyour macro.cfg needs to have the correct name
of your macro
should be dlpp for you I think
and maybe update the co-ords so it fits
m
Mariam Zanaty
06/18/2021, 9:03 PMI don't understand this
I'll change the name
But how to adjust the coordinates?
depending on what?
m
Matt Venn
06/18/2021, 9:06 PMin that file
how big is your macro?
m
Mariam Zanaty
06/18/2021, 9:08 PM900um * 600um
m
Matt Venn
06/18/2021, 9:09 PMok so it should fit with no adjustment
just change mprj to dlpp and see what happens
m
Mariam Zanaty
06/18/2021, 9:09 PMAlso I left the name of the instance of the top module as it is mprj
inside the user_project_wrapper
m
Matt Venn
06/18/2021, 9:10 PMbut the name of your macro is not mprj it's dlpp
m
Mariam Zanaty
06/18/2021, 9:10 PMokay
wil adjust this and try again
same error:(
I may be wrong
Will adjust something and run again
m
Matt Venn
06/18/2021, 9:20 PMwhy don't you have mpw-two-c tag in your tree?
m
Mariam Zanaty
06/18/2021, 9:22 PMIs this a critical problem?
For the macro.cfg
I adjusted it and got the same error
m
Matt Venn
06/18/2021, 9:23 PMyou will probably fail the precheck if your repo doesn't match mpw-two-c closely enough
m
Mariam Zanaty
06/18/2021, 9:24 PMOkay will fork it again
m
Matt Venn
06/18/2021, 9:24 PMand maybe makefiles/config are different enough to make configuration changes
m
Mariam Zanaty
06/18/2021, 9:25 PMOkay I'll adjust this
m
Matt Venn
06/18/2021, 9:25 PMI don't think that's why the macro stuff is failing tho
👍 1
m
Mariam Zanaty
06/18/2021, 9:25 PMWould you please take a look at my config.tcl and user_project_wrapper.v
They are the only files I edited
I think it would be in the config.tcl
m
Matt Venn
06/18/2021, 9:26 PMyeah, I'm sure it's the macro.cfg
but you said you've tried it with mpll
just trying it here
I don't know why you have changed the settings in the config
you have commented out the line that reads the macro.cfg, that's why that doesn't work
ok, I've got to go. good luck getting it ready
m
Mariam Zanaty
06/18/2021, 9:35 PMFor this
Okay
@Matt Venn Thank you for help:)
