TrueChip is a Verification IP specialist. For more than 10 years they have provided verification IP’s, like USB, PCIe, Ethernet, Memory, AMBA, Display RISC V and many more. They have an extensive portfolio including a very interesting product that is “TruEYE™️ GUI” which is a debugger helper tool for the verifications IPs.
Many times i notice people “kind of afraid” of some protocol, trying to avoid the usage because “it’s complicated”, I decide to go in-depth in one and show that maybe it’s not so complicated after all. First challenge is choosing the protocol and decide about the Ethernet, because this protocol… Read More
In the last article i write about the Data Link Layer, in this article i’ll write about the Transaction Layer.
This layer’s primary responsibility is to create PCI Express request and completion transactions. It has both transmit functions for outgoing transactions, and receive functions for incoming transactions.… Read More
In the last article, i wrote about the physical layer, now let’s take a look in the next layer the data link layer.
The Data Link Layer serves as the “gatekeeper” for each individual link within a PCI Express system. It ensures that the data being sent back and forth across the link is correct and received in the same order it
The USB protocol is a very complex protocol, so there is no way i can explain every detail in a post, but i can let much more easy to understand what happens in a bit level.
There isn’t much good material for easy understand about USB, so i made some assumptions for make easier explain everything. In this post i’ll explain… Read More
In the last article, I wrote about the PCIe basic concepts. This article will reach the physical layer of the PCIe standard.
The lowest PCI Express architectural layer is the Physical Layer. This layer is responsible for actually sending and receiving all the data to be sent across the PCI Express link. The Physical Layer interacts… Read More
This is another post that was requested by a user, and as always i’ll do my best to put in a few articles the basic information that you’ll need to understand how it works at depth level.
PCI Express (or PCIe) is a high-speed serial computer expansion bus designed to replace the older PCI, PCI-X and AGP standards.
The first… Read More
