Hi Mugundhan vijayaraghavan, Thank you for prompt reply. In the New version of mlib_devel 2022a, 'explicit_period', 'Explicit', ... in bi_real_unscr_2x_init.m in line 191, 'explicit_period', 'Explicit', ... in bi_real_unscr_4x_init.m in line 267, The difference is in coeff_gen_init.m reuse_block(blk, 'en', 'xbsIndex_r4/Constant', ... '',... removing '',... extra line. which I changed as you suggested also gave an error. update_casper_blocks(bdroot), can't update fft_wideband_real block and delete itself from the design. File: coeff_gen_init.m Line: 585 Column: 20 Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.
