Re: [myhdl-list] fixbv to current version of myhdl

[Jose M. G. C. <ch...@gm...>]

Dear all,

I have created a series of new types that allow to work with fixed point and is compatible with the fixed point from VHDL. I am still working on it, but it is presently compatible with GHDL, vcom and symplify.

I have not published it before because it uses a new base class, bitarray. I have also created classes for the signed and unsigned types. It still requires some tunning, because it is slower than intbv, as it is fully object oriented, which adds some overhead.

I do not know how to proceed as the number of changes is quite large. And I wanted to discuss it before hand, but as I saw this mail, I thought it could be useful.

In brief, the package is in git, under the user jmgc, fork numeric.

And Jan, if you think it can be added to myhdl, please, tell me how I shall proceed.

Just a last comment, I have not made a Verilog version because I lack the knowledge. But it should not be difficult to make functions that provide this functionality. There is a group of functions in opencores that can serve as a base.

Best regards,

Jose M.
