1. case description
when running bscan, a serials of pins need to be controlled to 1 by tdr;
a static dft signal with default value1 was registered by register_static_dft_signal_names, added as control point of those pins;
however, values are not loaded in tdr through jtag network;
2. invoke iproc
define command below before process_patterns_specification:
iProcsForModule $block
iProc set_tdr {} {
iWrite <tdr_sri_inst>.tdr 0b1 #depend on the tdr number within the inst
iApply
}
read_config_data -in <pattern_spec>/Patterns(JtagBscanPatterns) -from_string {
ProcdureStep(set_tdr_0) {
iCall(set_tdr) { }
}
}
3. ps
may need to reset proc after the icall because that will reset those tdr to 0 again.
