Hi, I am thinking of using Verilog for a project I am working on. Originally I was going to use a processor core (and C) on an environment someone set up for me in VHDL/Verilog, then I thought of using FpgaC and doing it myself, and now I'm more or less decided on using Verilog to do most of it (minus the hardware stuff, after initial development and simulation). My first questions, ...

Greetings: I am reading J Bhasker's "Verilog HDL Synthesis" along with "A Verilog Primer" in order to learn not only Verilog, but how to make sure I can model designs in a way that is synthesizable. What I have just learned is that the synthesis system (such as if I am using Xilinx ISE Webpack and it's associated synthesis tools) dictates what style must be followed, because one syst...

Hi, Currently I have verilog design files ready for a CPLD implementation and am planning to use a Atmel AT15xx series CPLD. But I am having difficulty in finding the right Atmel development software. As per the Atmel website, Prochip supports Verilog, but when installed I am not able to compile the Verilog design. Is there any other tool I can use to get the edif file from my Verilog...

HI all, I am a student. I am new to verilog and FPGA. I have a question. How do I use the 16x2 LCD which is on the development board? I have a verilog code which I want the LCD to load the ASCII char from the verilog code I written. The verilog code is just a few shift register acting like a LUT (look up table). Is there any way i can control the 16x2 LCD or is there any macro? I r...

We need to code some modules in both VHDL and Verilog and would like to use a parameter/generic to control inferring sync or async resets. Is there a clean way to code this that is similar in both VHDL and Verilog? For example, we could try to use `define in Verilog, but this won't port well to VHDL. I don't see how wen can use generate statements in Verilog to do this nicely, either. ...

Hi all, I am currently learning VHDL step by step, but I noticed there are also quite a lot of projects written in verilog. So, for somebody who knows the basis, what would be best? - First get a very good knowledge of VHDL and then start with verilog - or learn vhdl and verilog at the same time (as the two languages do offer simular features).

I am finally going to learn Verilog for real after using VHDL for 15 years. I've done a little work with Verilog and found it relatively easy to use. Now I want to learn the details and especially how not to make mistakes. VHDL has the problem of not letting you do things unless you make it explicitly clear what you want to do. My understanding is that Verilog will let you not specify f...

Hi, I am trying create verilog module that can support parameterized instance name. I understand that the signal width and other such things can be parameterized. But can we also parameterize the module instance name? In following code, I am curious if there is any way SomeDynamicInstanceName can be parameterized also? I can try to use system verilog if that can help here M

Can anybody recommend a good PC-based verilog simulator for substantially less than $4500? I am a new hire at a company which spent big bucks on ModelSim just two years ago. Unfortunately we purchased VHDL and I am a verilog designer. We have a tight schedule so I will stick with the familiar language. I would use the VHDL simulator but Xilinx tools won't put out a VHDL model from verilog sourc...

This is the first project I've done in Verilog in many years. With a long history in VHDL I have a new perspective and am seeing Verilog in a different way. I am finding some of the differences to be pretty interesting actually. I've already commented on the lack of the wildcard sensitivity only to find that VHDL has recently added this. Now I am learning how Verilog allows hierarchical...
