I am running some VHDL through ModelSim. Each error and warning has its own error code (like this: (vcom-1292) Slice range direction "downto" specified in slice with prefix of unknown direction. This is just an example message; I understand what it means.

I assume that Mentor has a list of all possible error codes and a more elaborate description of what they mean, and how to avoid them. I did not find this error code in the PDFs that come with ModelSim, nor did I find it through Google. Any pointers anybody?

There is a modelsim command called verror with an -all option to list them all, and other options to inspect the messages further.

    @Philippe: I was thinking primarily of Xilinx ISE/EDK, though I don't think this exists for the Altera tools either... happy to be corrected! In any case, even a definitive and comprehensive list of cryptic uninformative error messages isn't much help. – Saar Drimer Jan 26 '11 at 19:31
  • @Saar have you tried the verror command that Jan talks about? It _also_ gives a longer (4 lines) explanation for each of the short cryptic messages. Looks very useful – Philippe Jan 27 '11 at 19:54

if you are interested in finding out information about a certain error then use the verror command in the Questasim GUI. verror Better than going through the entire list. :)
