Welcome to HT-Lab
On this site you will find several FPGA/ASIC IP cores, some EDA Utilities and HowTo documents. Most of the IP Cores are written in generic VHDL and supplied in full source.
If you have any questions or comments please use the feedback form. For commercial inquiries you can contact HT-Lab via sales at ht-lab dot com.
If you are looking for the CPU86 8086 IP Core then click here (updated 25/07/14).
Need to convert VHDL to SystemC? try the alpha release of vh2sc.exe.
Interested in SystemC Synthesis? then check out SystemCrafters.
Looking for some high-quality prototype boards, need some custom boards? Navigate to Enterpoint FPGA and Asic Design.
Do you know VHDL? then try to answer this question, .............. the correct answer is here. If you are learning VHDL then this VHDL handbook might be useful. VHDL2008 has been approved by Accellera, Jim Lewis has an excellent presentation on some of the language enhancements.
If you are interested or involved in FPGA designs for fault tolerant systems, avionics, space or reconfigurable hardware then the yearly MAPLD conference is the place to be. Details of this excellent conference can be found at KLABS.
Focus is a product from FishTail Design Automation which automatically detect false and multi-cycle path in your design. The output is a set of SDC constraints which can be used for Synthesis, P&R and STA, see EEDESIGN article here.
If you are serious about programming in TCL/TK I would definitely recommend attending the excellent TCL/TK Doulos courses. You will not only learn how to program in TCL/TK but also learn how to use it with Modelsim.
Solidify is a Static Verification (property checker) tool from Averant Inc. Using Solidify the user can fully validate his design using Averant's HPL language, SVA or PSL. Solidify also contains an automatic property generation option which can be used to validate multi-cycle path constraints, check for unreachable states and deadlock in FSMs, deadcode, array boundary violations, tri-state violations and more.
While we are on the subject of assertions, this is how you should use assertions/report command (thanks to BlueARC in the UK :-)
Looking for a JTAG on-chip FPGA/ASIC debugger on steroids? would like to create a hardware testbench?, want to translate SVA/PSL into a hardware monitors? then try Temento's DiaLite!
