Hello everyone......I have a MacBook so can't install vivado design suit (not available for Mac and it's like 300gb I don't have the storage for it ), I'm using eda playground on web

In vivados xdc-files, is it possible to do calculations? So e.g. instead of providing a clock period I could provide the frequency and calculate the period from it?

@gKarthikSai hi , If Vivado Design Suite isn't available for your Mac, and you don't have the storage for it anyway, you're doing the right thing by using EDA Playground online. Keep using it for your design needs

Navadeep•3/20/24, 7:10 AM

yes, this is something very possible. In your example, you can be -divide_by like this

Manuel•3/20/24, 7:16 AM

Oh, no I don't want to derive a clock from another, but do actual calculations where the result can be stored to a variable. Using this for a clock was just an example.

Navadeep•3/20/24, 7:26 AM

Okay, I don't see a way to do math operations like that and variable assignments within .xdc

Ok, I feared that there is no way. Thanks nonetheless

, Please I really need to know what happens if there's no idle task in an RTOS? Does the system automatically generate one? And besides consuming CPU time, what other roles do idle tasks play?

i have added this block before thr t_axis_data of the dma what do you think: module EndianSwap(
input [31:0] InputData,
output reg [31:0] OutputData
);

always @ (InputData)
begin
OutputData[31:24] = InputData[7:0];
OutputData[23:16] = InputData[15:8];
OutputData[15:8] = InputData[23:16];
OutputData[7:0] = InputData[31:24];
end

AJAY KUMAR V•3/21/24, 1:52 AM

Sorry for the late reply @Phoenix
The internship was related to TI's TIVA and SimpleLink based low speed driver integration and product testing. I'm interested in IoT as well.
The startup is working on smart and handheld medical equipment development and gives service to redesign of system with new features as per requirement.
Thank you for asking
