FAQ
ispLever Classic 2.1 and below: Why does the D Flip-Flop in the post-fit equation of ispLever Classic contain 2 D inputs (D.X1 & D.X2)?
Description: The ABEL engine can extract XOR (exclusive OR) gates wherever possible, it generally gives better Fmax for most designs, so it is the default setting. Compared to the AND-OR logic gate, the XOR logic gate reduces the product term, and then routing complexity/time decreases and Fmax…
FAQ
ispLEVER Classic / Installation: What to do if error pops out when starting ispLEVER Classic "Can't read the ini file."?
Description:At start up, ispLEVER looks for an initialization file that is normally located under the lsc_env file (which normally sits directly under the C: drive). If ispLEVER cannot find this file (e.g. C:\lsc_env\lsc_1_4.ini), then the user will get this error. This error may also occur due to…
FAQ
ispLEVER Classic v1.8: Does the software support Mixed Verilog/VHDL as described in the ispLEVER Classic Installation Guide?
Solution: Classic does not support a mixed language project. Note that when you create a project, you have to choose a project type. Mixed language is not one of these. ispLEVER and Diamond do support mixed language but not Classic.The workaround is to open the sources in Synplify Pro and create an…
FAQ
