Simulink 中并行转串行模块的问题
我正在尝试将从 DQPSK 解调器(类型:UFix2_0)发出的输入字转换为串行流。
因此,我在 Simulink 中使用 Xilinx 库的并行转串行模块。
但我无法使用该块,出现以下错误:
“Simulink 系统周期”设置 在此系统生成器令牌上不是 适用于所使用的费率 设计。
当前设置为:1 An 适当的设置是:1/2"
我也尝试更改系统生成器的设置,但它似乎不起作用。
知道我可能会出错的地方。任何其他方法也会有帮助。
谢谢
I am trying to convert the input word coming out of the DQPSK Demodulator (Type : UFix2_0) to a serial stream.
So I am using the Parallel-to-Serial Block of Xilinx Library in Simulink.
But I am not able to use the block, I get the following error :
"The Simulink system period" setting
on this System Generator token is not
appropriate for the rates used in the
design.The current setting is: 1 An
appropriate setting is: 1/2 "
I tried to change the setting the System Generator as well, but It does not seem to work as well.
Any idea where I might be going wrong. Any other approach would be helpful as well.
Thanks

在 Xilinx Sysgen 文档中搜索“simulink system period”
入门指南 (1) 展示了如何计算具有多个速率的系统中的 simulink 系统周期(通过使用并行到串行获得) 堵塞)。基本上,simulink 系统周期是模型中出现的采样周期的最大公分母。看起来系统周期的设置方式与速率更改块之前和之后的周期(并行与串行)之间存在冲突。
Search for "simulink system period" in the Xilinx Sysgen documentation
The getting started guide (1) shows how to calculate the simulink system periods in a system with multiple rates (which you get by using the parallel to serial block). Basically the simulink system period is the greatest common denominator of the sample periods that appear in the model. It looks like you have a conflict between how the system period is set and the periods before and after your rate changing block (parallel to serial).
