How the slew-rate and drive strength affect the output signal of the FPGA?

Can someone describe the difference between the drive strength and the slew-rate preferences in Lattice FPGA?

Datasheet Parameter for Drive Strength

I am looking at a TI level translator and need a certain current drive strength. However, in general, what datasheet parameter corresponds to this so I can make sure I provide enough drive?

50 Ohm TTL Drive Strength

I'm designing a device that will output TTL (0-5V) over a 50 Ohm coax to an NI PXie-6672 with programmable 50 Ohm termination. I'm wondering if I will truly need 100mA of drive strength from my output - from what I understand parallel line…

Max number of logic units / gates per logic-unit-output wire: FPGA

I couldn't find any info about this. Is there a general rule or does it change for all vendors(altera or xilinx)? Lets assume I have a flip flop and I want to wire 10 flip-flops to its output. Normally, in my university lab using cheap (1$-2$) ICs,…

AVR32 Drive Strength

The UC3C Datasheet doesn't provide a clear explanation about "drive strength", how it behaves and the side effects in projects. After fabricating my board I realized I placed a LED on a x1 strength pin (AVR32UC3C2512C pin PB00) and I calculate a…

GPIO current drive strength test circuit

I have GPIO channels in my controller. The controller manufacturer does not know exact number of drive strength of the GPIOs. The controller is a digital signal processor (DSP) board. I want to control a stepper motor using my GPOIs, but the input…

Pin strength configuration

Please, help me understand the specsheet on page 2-22. The table says that 3.3V standard supports 12mA drive strength, but there is also a "software" defined strength. What is it? There is also a "wide range" (table 2-29 second row, and notes 1 and…
