Reusable Integration Framework for FPGA Accelerators (RIFFA) is a simple framework for communicating data from a host CPU to a FPGA via a PCI-E. RIFFA supports Windows/Linux, Altera/Xilinx, with bindings for C/C++, Python, MATLAB and Java.

One of my favorite part of UG949: RTL designer should know into which one primitives (and how many logic levels) infers strings of HDL

Following command retrieves
the TEMPERATURE property from connected FPGA:
get_property TEMPERATURE [get_hw_sysmons]
To report all properties of HW_SYSMON use this in TCL console: report_property -all [lindex [get_hw_sysmons] 0]

Bitstream Interpretation Library (BIL) for reading and interpreting bitstream files targeted at Xilinx FPGA:

- Configuration raw data extraction from bitstream files
- XDL design regeneration out of configuration raw data
- Automated configuration mapping analyzation of a device

Optionally run optimization if there are timing violations after placement

if {[ get_property SLACK [ get_timing_paths -max_paths 1 -nworst 1 -setup ] ] < 0 } {
    puts "INFO :: Found setup timing violations. Running physical optimization once."
