openlane/Module call problem

Could it be because "set ::env(VERILOG_FILES_BLACKBOX) ""? BLACKBOX this parameter?

Each Macro are separately Hardened and Integrated as block box at user_project_wrapper. If you include all the RTL at user_project_wrapper tool will not be able harden full design in one go.
You need to first run sub macro harden scripts and followed by user_project_wrapper final integration

make pinmux
make uart_i2cm_usb_spi_top
make wb_host
make ycr_core_top
make ycr_iconnect
make qspim_top
make wb_interconnect
make ycr_intf

make user_project_wrapper

Our team had questions, why separate integrations? Instead of using the total project which contains all the RTL code to integrate at once? Is there a flaw in doing this？

Sorry for the late reply, thank you very much for your answer.
Wouldn't it be more automatic to execute the "make master project" only once?
What is the purpose of this separate integration?

Current Makefile flow does call automatically all the sub macro. I prefer to run the each macro on need basis to avoid long run time. As most of the time design changes are specific to one macro. For each top-level integration update, you don't need to re-harden all the block.
