Hi Nikita The estimate_fpga_clock() functionality is based on the implementation of the sys_block_counter instance in ../mlib_devel/jasper_library/yellow_blocks/sys_block.py and ../ mlib_devel/jasper_library/hdl_sources/sys_block/sys_block_counter.v. Kindly check if these implementations exist in the mlib_devel repository you are using. Else, try to test using h <goog_10357047> ttps://github.com/casper-astro/mlib_devel/ <https://github.com/casper-astro/mlib_devel/> or https://github.com/ska-sa/mlib_devel/
Also the functionality seems to have been tested while the IP clock source was selected as sys_clk in the RED_PITAYA platform block in Simulink. I hope that helps.
