complement of dividend, divisor, respectively. module deci_test(dividend, divisor, dividend_sign, divisor_sign, out_sign, dividend_comp, divisor_comp, int_part, decip_part, int_thousands, int_hundreds, int_tens, int_ones, decip_tens, decip_ones)

To debug this code by simulation, I added so many output regs in the code. What's wrong with my code? I'm expecting the loop to terminate after repeating 7 times(from i=0 to i=6), but the error occurs. Then finally turning these into BCD, respectively.Įxpecting this code should be working, however, I got an error message that "For loop stop condition should depend on loop variable or be static." on the line for(i = 6 i >= 0 i = i - 1) begin. So, to get the result, I get the signed input(dividend, divisor), convert these into complements(dividend_comp, divisor_comp), and get separate results(int_part, decip_part) thorugh the dividing process.

By operating /100 and %100 on this result 1333.33., you can get integer part 13, and decimal points part 33. To avoid complicated algorithms to express out the decimal points, by multiplying 100 to dividend and dividing this(100*dividend) by divisor, I could get the result to the second place. The module should yield the result in the format "iiii.dd"(i for integer part, d for under decimal points). I was developing the 'dividing module', by making some tricks to seemingly calculate the decimal points.

It seems libfreetype linked specifically to the libpng version 1.6 library rather than using whatever version library is installed. Working back up a level I found that this library is required by the "libfreetype" library, which manages Freetype fonts. However, merely copying this library from an Ubuntu 16.04 system into the Xilinx library directory didn't fix the problem - ISE continued to use the newer library. Ubuntu 16.04 uses version 1.2 of this library, while 18.04 provides version 1.6.

The library that causes the problem is called "libpng", which handles Portable Network Graphic (PNG) format files. I figured it was worth trying to add a copy of the newly problematic library taken from an Ubuntu 16.04 installation to Xilinx's collection of libraries. This is similar to what Windows used to do, except Linux provides a means for making it work without trashing the libraries used by other applications. So they started collecting the libraries they used and shipped them with the programs.

Long ago, Xilinx realized that they would face a serious challenge trying to keep ISE and related software products running on the infinite variety of Linux flavors. A web search showed that someone else "fixed" this problem by deleting that font, but that seemed like a bad idea to me. Using the "strace" utility I identified that the problem occurs when attempting to process a particular font. Libpng warning: Application jmp_buf size changed As a long-time Linux developer I recognized right off the bat that some library ISE uses must have changed in an incompatible manner.
