weak pull up和weak pull down是什么意思啊? 一个输入引脚,想在库里找一个合适的pad,发现了一种PIC pad和PICD pad,PICD pad好象就是多加了一个NMOS管,具有weak pull down功能,可以在输入为RL(resistive low)时让输出为0,我有点不太清楚。 RL是什么意思呢,这样的一个weak pull down具体有什么功能呢?

I'm using Quartus Prime Lite Editon 18.0.0 version to develop MAX V CPLD. I want set the un-used pin to weak pull-up. Please let me know where can I find the "Quartus Prime Lite Edition - Setting File Reference Manual". And please let me know ...

I.e. I see 0.8v on the pin if I use a 5K resistor to pull to ground. I noticed that if I disable the weak-pull up on C2 then the leakage current on C1/D1 vanishes. Note that in my design C2 is actually an unused pin, the weak pull-up was on by default by the 'as...
pullup、pulldown看做是门级原语,assign语句看做是RTL。 SystemVerilog接口不允许门级原语。如果是用来写ip,应该使用assign语句。 一些工具,像静态时序分析,期望用门级原语建模,而不是RTL,这时应该使用pullup、pulldown来代替。 pullup、pulldown默认的驱动强度是pull,assign语句默认的驱动强度是strong。
Have a great day, T1040 Data Sheet also says “This pull-up is designed such that it can be overpowered by an external 4.7 k resistor. However, if the
I see. You are using the weak pull-ups, not for the purpose of avoiding floating inputs on the FPGA, but also for providing a defined power-up output level. I assumed that in those applications where the power-up level is critical, an external pull-up or pull-down ...
