bist_clk ,bist_test and bist_result are bist logic signal
who can give some explain about these signals,such as bist_result ,a signal will output what waveform in bist mode?

the output of bist result is fail or pass, no standard waveform , you can detect the result value is ok

bist_clk: clk for bist logic;

bist_test: bist test enable signal;

bist_result: indicate bist test pass or fail, it is a level signal,

there should be a another signal

bist_finished: indicate bist test is finish.

we can determine the bist test is pass or fail by bist_result and bist_finished,

if bist test has finished , bist_result indicates test is pass or fail;

Yes bist_result is a logic signal. You will get this result after making a comparing between two output datas, which known good data and output form DUT.

The final result is either pass/fail
