Here's a summary of the features/limitations of the software:Īltera's Quartus II or the free Web Edition
Scale modelsim altera vertically full#
Scale modelsim altera vertically software#
The free software is usually fine to start with because Altera's free software is named Quartus II Web Edition, which is a scaled-down version of the full Quartus II software.Xilinx's free software is named ISE WebPack, which is a scaled-down version of the full ISE software.Programming through special cables (JTAG).įPGA vendors provide a free software that supports low to medium density FPGA devices, and a full (non-free) version of the same software that supports the big FPGA devices.The second one is TDM_record ( ), which is also inside "tdm.c".FPGA vendors provide software that support their devices.In particular, I want to deprecate TDM_traverse_rt_tree ( ), and have adding a new TDM detail node integrated into pathfinder_update_one_cost ( ). This error makes me realize that there is a more serious problem (or bug) in Hanyu's code. When I finish coding and run it, I get an error ("Error: Occupancies do not match."). As a first step, I write a TDM_opt_occ_1 ( ), which does not use MAX_BUF and deprecates TDM_opt_occ ( ).

There are two loops, which are responsible for the long runtime.

Therefore, I would like to optimize Hanyu's code to make it run faster. A drawback of Hanyu's code is that it runs very slow.

When I have a bitmap for a net, I can predict in which ucycles the rr nodes used for routing this net are. If we divide the user cycle into ucycles, a bitmap can be computed for each cell or net. From a timing perspective, each cell or net along the path can be "binned" into different ucycles. The order of bits is not usually configurable, but data can be byte-swapped only before sending.Ī path in the circuit DAG consists of several cells and several nets.

Also possible, but rarely used, is "big endian" or MSB (Most Significant Bit) first serial communications (see Endianness). This standard is also referred to as "little endian". Most serial communications designs send the data bits within each byte LSB (Least Significant Bit) first. The resulting trace is a plot of voltage against time, with the more distant past on the left and the more recent past on the right.įor endianness issue in serial communications, check here: Another control, the vertical control, sets the scale of the vertical deflection, and is calibrated in volts per division. If the input voltage departs from zero, the trace is deflected either upwards (normally for positive polarity) or downwards (negative). One of the controls, the timebase control, sets the speed at which the line is drawn, and is calibrated in seconds or decimal fractions of a second per division. In its simplest mode, the oscilloscope repeatedly draws a horizontal line called the trace across the middle of the screen from left to right.
