Verilog : Functions | Verilog Tutorial | Verilog

We’re also going to parallel the Perl code with a pure Verilog function, just like our local parameters.

However, Verilog-2001 allows the use of a function call to evaluate theMSB or LSB of a width declaration

The presence of feedback loops should be avoided at any stage of thedesign, by periodically checking for it, using the lint or synthesis tools.

The XST documentation says that Verilog functions are fully supported. I was frustrated today to discover that this is not the case. I was trying to make a library for handling fixed point arithmetic. Module instantiation overhead in Verilog is quite high in terms of lines of code and excess verbiage. All the code I need to use is combinational, so the natural thing to do is have one module with all my functions and parameters which control the representation of the fixed point numbers. After this, I can make instances of the library module with the various fixed point representations I need and use the functions.

Metabolic Pathways and Control:
Location of carbohydrate, lipid and protein metabolism pathways with respect to one another; common metabolic sources and fates; compartmentalization of metabolic pathways; regulation of carbohydrate, lipid and protein metabolism; synthesis, storage and utilization of energy sources; thermodynamic relationships among pathways

The issue is that the tools don’t seem to implement the built-in Verilog floating point functions during elaboration. Essentially, the synthesis tool needs to run the initial block in order to know how to populate the lookup table. In general, the tools can do this. However, if they catch wind of a float value, they tuck their tail between their legs and run.

The plan stage involves reviewing the functional specification of the design and determining what functionality must be verified at each development stage of the design IP. It is a goal of the verification plan to verify full functionality at the highest level of abstraction. Tests should be run post synthesis to ensure a total functional match between abstract model and implementation. As the verification plan is refined, it is not necessary to re-run all tests at these intermediate stages. Formal equivalence checking can be used where possible, or sequences can be re-used at subsequent stages to regress what has already been verified.

If anyone knows of a software floating point library written purely in Verilog, please let me know. We could then use that to trick the synthesis tools into doing what we want.

In an older , I discuss a Verilog Preprocessor that I wrote years ago. In the old days of Verilog ’95, preprocessors like this were practically required. The language was missing lots of features that made external solutions necessary, but got largely fixed with Verilog 2001 and Verilog 2005. Now with Systemverilog, things are even better. However, sometimes tools don’t support all of the language features. In the , we discovered that the FPGA synthesis tools can’t handle the floating point functions used in the ROM initialization code.

SystemVerilog for Designers - Doulos

My last post introduced an algorithm for finding the log base 2 of a fixed point number. However, it had a gotcha. It had to use some floating point functions to initialize a table, and even though it is not synthesizing floating point, ISE, Vivado, and Quartus II all refuse to synthesize the design. What should we do?
