Subject: Re: [oc] verilog or vhdl - Let's finish this discussion ?
Vic nad tha other members,
Excuse me but you are been to enthusiat whne you say that VHDL is only
for geeks and Degree students and researchers.
I work with both languages Verilog and VHDL. Memory is better to be made
using Verilog, because synthesizers like Leonardo Spectrum see that the
code defined is a memory and use the bit rams of a device if available,
in VHSDl not ever this happens but in VHDL you could create more complex
Structures like matrix of 12x12 (example only) std_logc_vectors(32 dowto
0) so 12x12x32 and its a two dimensional matrrix now try to do this on
Verilog is almost impossible. Verilog have only 17 nos synthesizable
reserved words like fork and join ( i don't readed tha Verilog 2001
specification yet, only in Quartus II ver 3.0 for example was added this
kind of support), but VHDL has a bigger list of non synthesizable
reserved words.
YES Verilog it's simple very simple, YES VHDL is more complex but not
much more than Verilog, you only need to choose the best option for your
project, entirely or some components of your projects. Finally the best
langauage is that work, if Java did the work good (this was a little
joke), try to get the best approach combinig the advance of two
languages is the better so if Verilog is better to define memories, use
Verilog for this, i fVHDL is better to define more complex strtuctures
so use, don't close your horizons for only one language try use teh
necessary tools to make your project in a adequate time, with adequate
pricing.
