最近想使用matlab模擬PLL的behavior，

# A- s7 c# j7 o3 V; ?但block接好後，卻無法模擬，出現下面error

At time 1.654088834175351e-009, simulation hits (1000) consecutive zero
, g2 \, k" w% Q( P# \crossings. Consecutive zero crossings will slow down the simulation or cause
the simulation to hang. To continue the simulation, you may 1) Try using
/ {3 \' R5 n6 |9 F1 Y* TAdaptive zero-crossing detection algorithm or 2) Disable the zero crossing of
the blocks shown in the following table.
