For now you just have to wrap signals in an interface to keep them handy for a class to use.Īllow multi dimensional arrays with both types and widths:Īllow for seamless multidimensional array flipping: Pass signals directly into a class, but of course. Variable length arguments would be nice, make it easier to create a new display function with added parameters. That'd help for some of my randomized teesting Don't know how that works as I haven't used it yet.Īllow constant functions to call system tasks. Now onto the next improvement that I am excited about: Multiple Inheritance! The new SV 2012 now supports multiple inheritance by using an interface class. I have always resolved this using another method in cl_ext:īut now, with SV 2012, you can directly call new: So now I want to instantiate a cl_ext and point to it with a cl_base pointer. You can now call new from another object. So I've read up a bit on the newest SystemVerilog standard, SV 2012. # since rdesktop uses keymaps by default from /usr/local, and since rdesktop isn't installed there, we will cheat by creating a link to 'user' available keymaps # copy system installed rpm list (must do this to meet dependency requirements of desired apps) In my home directory I performed these steps:Įcho `%_dbpath /home/ /rpmdb' | cat > ~/.rpmmacrosĮcho '%_topdir /home/ /rpmtop' | cat > ~/.rpmmacrosĮcho '%_tmppath /home/ /rpmtmp' | cat > ~/.rpmmacros

Kudos to: for showing me how to do this.
Recently I came across a challenge of installing remote desktop without root privileges. Now creating a is as easy as calling a::create(). I believe others refer to this as a factory create function or something like that. Much nicer than the replication mechanism.Ībout the create function: SystemVerilog doesn't allow you to call new on a class type so I use a create function instead: This uses the default syntax for filling in an array. When I was passing a non array, it would work b/c the declaration included an assignment:Ī_class a_instance = ' The initial statement is too late, a null object was passed in and that's what the object and modules will have. Has something to do with object and module creation running before initial lines. The biggest issue is that a_instance isn't yet initialized.įor(genvar i = 0 i < num i++) a_instance = new() I also want to pass these objects to modules and other created objects.ī_class b_instance = new (a_instance) So I'm updating one of my testbenches and I want to create an array of objects. B/c each round of key expansion produces 192 bits (24 bytes) and each round of encryption uses 16 bytes, you have to loop through 1.5 rounds of encryption before starting a new line of key expansion. For 256, it is the same round every 2 times. If you want to generate AES 128 on the fly, then it is the same sequence for each round of encryption. The biggest difficulty is on the fly key generation. AES 256 is easier to implement than AES 192. Also decryption's inverse mix columns step requires 4 multiply look-up tables as opposed to 2 for encryption's mix columns step.Ĥ.

To perform decryption, you MUST perform full key expansion to get the final key. You can actually generate the keys on the fly. What I mean is that to perform encryption you just need the key to begin with. Realize that every step of AES (key generation, adding round keys, substitute bytes, shifting rown, and mixing columns) require Galois operations. Wherever it says subtract it is the same operation as add. So when they say multiply, this is what they mean.Ģ. I don't really know much about what a Galois field is, but it is an alternate universe when it comes to mathematics. You will need a function to perform gmul. These may help you in conjunction with other tutorials.ġ. But I will tell you some interesting things that I learned about AES. So if you are looking for that, then you can turn right around and go. I'm not gonna teach you how to perform AES encryption or decryption.
