[Ghdl-discuss] Use of vpi to inspect signals down in the hierarchy

Hi, I am running a ghdl simulation of mc8051 and want to do some profiling by using textio to write the program counter to file. I have found by searching google that it is not possible to do this since the program counter is a couple of levels down in the hierarchy. I have so far used gtkwave on

[Ghdl-discuss] My real values are not updated according to gtkwave

Hi, I am simulating some code involving reals. When I use ghdl and dump the data to ghw and inspect with gtkwave, the adc_real(i) values get updated twice and then never more. When simulating with modelsim, I see that the same code result in adc_real values being updated with one clock cycle

Re: [Ghdl-discuss] Debian package maintainer has retired

Sometimes it is better to move the troubled kid out of the community. Having a clean-room version of the gcc version compatible with ghdl in a location where apt-get cannot touch it seems very much a way around the current problem. Problem for me as a GHDL user is that building gcc in /usr/local

[Ghdl-discuss] ghdl with qemu to emulate SoC FPGA

Hi, I am currently working on a SmartFusion2 project, and did some search on the web. I found several pages describing how to write bare-metal applications for ARM Cortex-M3 using qemu. I even found a project with efforts to make a virtual development environment for PCIe on github.

Re: [Ghdl-discuss] ghdl with qemu to emulate SoC FPGA

Hi, lots of answers I haven't got around to read properly, but I notice that my objectives were not clear. It all starts with the simple fact that we use SmartFusion2 in a design. We have prototypes ready and I have written a lot of VHDL for this board and a bare-metal Cortex-M3 application to

[Ghdl-discuss] Some changes I had to do on Debian stretch/sid to compile llvm from github

Hi, maybe this is already known, but I had to do a couple of modifications to get ghdl-llvm compiled as the gcc version is 5.2 and llvm is 3.6 In the 'configure' script, I changed the test for llvm-config to llvm-config-3.5 This will be overwritten by a git reset --hard unless something is done

Re: [Ghdl-discuss] Some changes I had to do on Debian stretch/sid to compile llvm from github

Hi again. In the end I chose to install gnat-5 in Debian stretch/sid, and add update-alternatives for gcc, g++, clang++ ghdl compiles fine with gnat-5 and gcc/g++-5. It is having llvm 3.5 and llvm 3.6 installed at the same time which 'forces' me to add alternatives. I haven't tried using llvm

[Ghdl-discuss] Regarding issue #56

Hi, motivated by Tristan's push on #56, I decided to take cocotb+ghdl for a drive again. I had to modify a bit in cocotb ghdl makefile because there was an error, so I expect nobody to have cocotb+ghdl up and running yet. Does it make a difference if I compile ghdl with gcc or llvm for cocotb?

Hi, just pulled latest ghdl from github and rebuild the way I usually do: git pull make distclean ./configure --with-llvm-config make sudo make install First thing I notice is when building a project I have built before is: ghdl -m --ieee=synopsys mc8051_top_struc_cfg elaborate

Just an observation. When building with make, I see that gcc-5 and gcc are used like this example: gcc-5 -c -I./src -I./src/vhdl -I./src/psl -I./src/vhdl/translate -I./src/ghdldrv -I./src/grt -I./src/ortho -I./src/ortho/llvm-nodebug -I./src/ghdldrv -gnaty3befhkmr -gnatwae -gnatf -gnat05 -g -gnata
