请教解决buffer was too small
 

请教：我在用sinmulink对一个电力电子系统仿真时出现警告Warning: The specified buffer for 'sanxiangzhengliuqiao/RMS/T' was too small. During simulation, the buffer size was temporarily increased to 19456. In order to use Real-Time Workshop, you need to update the buffer size parameter.
找了很久 也不知道该怎么修改 特请教一下
